Comment (by nacin):

 PHP is not JavaScript, but even in JS, you assign these things to
 variables when it makes sense to do so. Closures are nice for one-off
 things. This is no longer so simple once you require adding it to multiple
 hooks. Why not a top-level function?

 Also of note, if you do use a closure but don't assign it to an accessible
 variable, it becomes impossible to remove that action later without
 calling remove_all_actions(). That is lame, and makes closures little
 suited beyond testing and internal implementations. For distributed work,
 they are best avoided.

 I don't have a specific objection to this, and PHP 5.4 [ ] syntax makes it
 somewhat elegant. But it does complicate an API that is, at the moment,
 quite simple.
