 One thing I wish I was able to do is pass multiple hooks to `add_action()`
 and `add_filter()`, so I could do stuff like this:


 {{{
 add_action( ["admin_print_styles-post.php", "admin_print_styles-post-
 new.php"], function() {
     echo 'Two in one!';
 } );
 }}}

 Currently If you want to use a closure you have to do something like

 {{{
 add_action( "admin_print_styles-post.php", $hook = function() {
     echo 'Two in one!';
 } );
 add_action( "admin_print_styles-post-new.php", $hook );
 }}}
