Comment:

 I've been wanting to do this for a while.

 I don't think it is a good idea to add this directly to do_action and
 apply_filters calls, as we need these to perform as fast as possible.
 Additionally, the patch as attached would break any action that has
 multiple args attached to it.

 Instead, I would suggest we issue a call {{{_deprecated_hook( name of
 hook, version, replacement, message )}}} just after the hook is executed,
 and use did_action() in _deprecated_hook() to see whether we should
 actually trigger a deprecated_hook_used action and issue the E_NOTICE (if
 WP_DEBUG).

 Might not be a bad idea to use _deprecated_action() and
 _deprecated_filter(), have one wrap the other, and simply use slightly
 different messages, just to be clear in both the source code and in the
 E_NOTICE that is produced.
