 * @description
 * Constructor for Python bool. Also used for builtin bool() function.

 * Sk.builtin.bool.true$ or Sk.builtin.bool.false$. These are defined in src/constant.js
 *
 * @extends {Sk.builtin.object}
 * 
 * @param  {(Object|number|boolean)} x Value to evaluate as true or false
 * @return {Sk.builtin.bool} Sk.builtin.bool.true$ if x is true, Sk.builtin.bool.false$ otherwise
