Comment (by joehoyle):

 If you are using closures, this isn't just syntactic sugar.


 {{{
 foreach ( array( 'sanitize_post', 'sanitize_user' ) as $hook ) {
   add_action( $hook, function() { return $foo; } );
 }
 }}}

 This will create 2 closure objects, whereas `add_action` supporting an
 array would only require 2 references to the same closure. (less memory
 usage, shared scope etc)

 You could always do

 {{{
 $func = function() { return $foo };

 foreach ( array( 'sanitize_post', 'sanitize_user' ) as $hook ) {
   add_action( $hook, $func );
 }
 }}}

 But that feels like it starts to get messy. I would rather create my own
 `add_actions` function than do the above, so I don't think it's a stretch
 to just add the functionality to `add_action`
