- * Pseudo selectors
- *
- * Pseudo selectors are available in three forms:
- *
- * 1. Filters are called when the selector is compiled and return a function
- * that has to return either false, or the results of `next()`.
- * 2. Pseudos are called on execution. They have to return a boolean.
- * 3. Subselects work like filters, but have an embedded selector that will be run separately.
- *
- * Filters are great if you want to do some pre-processing, or change the call order
- * of `next()` and your code.
- * Pseudos should be used to implement simple checks.
