/* |
|
* 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. |
