Comment (by gcorne):

 having priority would be great.

 The ability to control execution order is definitely worth having.

 I went ahead and had a go at adding a context parameter. See
 https://github.com/gcorne/WP-JS-
 Hooks/commit/e7ab26d9aae2f5383b8ec156454ce241bcb4a87e

 I also think that we should incorporate the ability to remove a specific
 hook based on {{{===}}} comparison. Something like:

 {{{

 var func = function() {
     // do awesome stuff
 };

 wp.hooks.addAction( 'foo', func );
 // lots of code

 wp.hooks.removeAction( 'foo', func );

 }}}

 We could either make the callback reference optional in {{{ removeAction()
 }}} and when not passed remove all, or perhaps create a separate method
 {{{ removeAllActions() }}}.
