4/*
5 * Pseudo selectors
6 *
7 * Pseudo selectors are available in three forms:
8 *
9 * 1. Filters are called when the selector is compiled and return a function
10 * that has to return either false, or the results of `next()`.
11 * 2. Pseudos are called on execution. They have to return a boolean.
12 * 3. Subselects work like filters, but have an embedded selector that will be run separately.
13 *
14 * Filters are great if you want to do some pre-processing, or change the call order
15 * of `next()` and your code.
16 * Pseudos should be used to implement simple checks.
