Comment (by dshafik):

 So, it was pointed out on
 [https://twitter.com/mrclay_org/status/412568250162368512 Twitter] that
 the callbacks are not always global functions.

 This patch will work on PHP 5.4+ where array notation callbacks can be
 used like `$foo()` but not in earlier versions, breaking BC.

 I'm going to tweak it some more today and see if I can't get a reasonable
 solution that works in all versions.
