/*
|

|
|
* 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.
