/**
 *
 * Notes on necessity for 'call()':
 *
 * Classes are callable in python to create an instance of the class. If
 * we're calling "C()" we cannot tell at the call site whether we're
 * calling a standard function, or instantiating a class.
 *
 * JS does not support user-level callables. So, we can't use the normal
 * prototype hierarchy to make the class inherit from a 'class' type
 * where the various tp$getattr, etc. methods would live.
 *
 * Instead, we must copy all the methods from the prototype of our class
 * type onto every instance of the class constructor function object.
 * That way, both "C()" and "C.tp$getattr(...)" can still work. This is
 * of course quite expensive.
 *
 * The alternative would be to indirect all calls (whether classes or
 * regular functions) through something like C.$call(...). In the case
 * of class construction, $call could then call the constructor after
 * munging arguments to pass them on. This would impose a penalty on
 * regular function calls unfortunately, as they would have to do the
 * same thing.
 *
 * Note that the same problem exists for function objects too (a "def"
 * creates a function object that also has properties). It just happens
 * that attributes on classes in python are much more useful and common
 * that the attributes on functions.
 *
 * Also note, that for full python compatibility we have to do the $call
 * method because any python object could have a __call__ method which
 * makes the python object callable too. So, unless we were to make
 * *all* objects simply (function(){...}) and use the dict to create
 * hierarchy, there would be no way to call that python user function. I
 * think I'm prepared to sacrifice __call__ support, or only support it
 * post-ECMA5 or something.
 *
 * Is using (function(){...}) as the only object type too crazy?
 * Probably. Better or worse than having two levels of function
 * invocation for every function call?
 *
 * For a class `C' with instance `inst' we have the following cases:
 *
 * 1. C.attr
 *
 * 2. C.staticmeth()
 *
 * 3. x = C.staticmeth; x()
 *
 * 4. inst = C()
 *
 * 5. inst.attr
 *
 * 6. inst.meth()
 *
 * 7. x = inst.meth; x()
 *
 * 8. inst(), where C defines a __call__
 *
 * Because in general these are accomplished by a helper function
 * (tp$getattr/setattr/slice/ass_slice/etc.) it seems appropriate to add
 * a call that generally just calls through, but sometimes handles the
 * unusual cases. Once ECMA-5 is more broadly supported we can revisit
 * and hopefully optimize.
 *
 * @param {Object} func the thing to call

 JS Beautifier
---------------

      http://jsbeautifier.org/

  Originally converted to javascript by Vital, <vital76@gmail.com>

  You are free to use this in any way you want, in case you find this useful or working for you.

  Usage:
    js_beautify(js_source_text);
    js_beautify(js_source_text, options);

  The options are:
    indent_size (default 4)          — indentation size,
    indent_char (default space)      — character to indent with,
    preserve_newlines (default true) — whether existing line breaks should be preserved,
    indent_level (default 0)         — initial indentation level, you probably won't need this ever,

    space_after_anon_function (default false) — if true, then space is added between "function ()"
            (jslint is happy about this); if false, then the common "function()" output is used.
    braces_on_own_line (default false) - ANSI / Allman brace style, each opening/closing brace gets its own line.

    e.g

    js_beautify(js_source_text, {indent_size: 1, indent_char: '\t'});

    This file creates a global JSON object containing two methods: stringify
    and parse.

        JSON.stringify(value, replacer, space)
            value       any JavaScript value, usually an object or array.

            replacer    an optional parameter that determines how object
                        values are stringified for objects. It can be a
                        function or an array of strings.

            space       an optional parameter that specifies the indentation
                        of nested structures. If it is omitted, the text will
                        be packed without extra whitespace. If it is a number,
                        it will specify the number of spaces to indent at each
                        level. If it is a string (such as '\t' or '&nbsp;'),
                        it contains the characters used to indent at each level.

            This method produces a JSON text from a JavaScript value.

            When an object value is found, if the object contains a toJSON
            method, its toJSON method will be called and the result will be
            stringified. A toJSON method does not serialize: it returns the
            value represented by the name/value pair that should be serialized,
            or undefined if nothing should be serialized. The toJSON method
            will be passed the key associated with the value, and this will be
            bound to the object holding the key.

            For example, this would serialize Dates as ISO strings.

                Date.prototype.toJSON = function (key) {
                    function f(n) {
                        // Format integers to have at least two digits.
                        return n < 10 ? '0' + n : n;
                    }

                    return this.getUTCFullYear()   + '-' +
                         f(this.getUTCMonth() + 1) + '-' +
                         f(this.getUTCDate())      + 'T' +
                         f(this.getUTCHours())     + ':' +
                         f(this.getUTCMinutes())   + ':' +
                         f(this.getUTCSeconds())   + 'Z';
                };

            You can provide an optional replacer method. It will be passed the
            key and value of each member, with this bound to the containing
            object. The value that is returned from your method will be
            serialized. If your method returns undefined, then the member will
            be excluded from the serialization.

            If the replacer parameter is an array of strings, then it will be
            used to select the members to be serialized. It filters the results
            such that only members with keys listed in the replacer array are
            stringified.

            Values that do not have JSON representations, such as undefined or
            functions, will not be serialized. Such values in objects will be
            dropped; in arrays they will be replaced with null. You can use
            a replacer function to replace those with JSON values.
            JSON.stringify(undefined) returns undefined.

            The optional space parameter produces a stringification of the
            value that is filled with line breaks and indentation to make it
            easier to read.

            If the space parameter is a non-empty string, then that string will
            be used for indentation. If the space parameter is a number, then
            the indentation will be that many spaces.

            Example:

            text = JSON.stringify(['e', {pluribus: 'unum'}]);
            // text is '["e",{"pluribus":"unum"}]'


            text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t');
            // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]'

            text = JSON.stringify([new Date()], function (key, value) {
                return this[key] instanceof Date ?
                    'Date(' + this[key] + ')' : value;
            });
            // text is '["Date(---current time---)"]'


        JSON.parse(text, reviver)
            This method parses a JSON text to produce an object or array.
            It can throw a SyntaxError exception.

            The optional reviver parameter is a function that can filter and
            transform the results. It receives each of the keys and values,
            and its return value is used instead of the original value.
            If it returns what it received, then the structure is not modified.
            If it returns undefined then the member is deleted.

            Example:

            // Parse the text. Values that look like ISO date strings will
            // be converted to Date objects.

            myData = JSON.parse(text, function (key, value) {
                var a;
                if (typeof value === 'string') {
                    a =
/^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value);
                    if (a) {
                        return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4],
                            +a[5], +a[6]));
                    }
                }
                return value;
            });
