Pd-l2ork has a feature where you can [r "arrayname_changed"]
and you'll get a bang when the array is modified with the mouse.
If you want a notification when using tabwrite/etc., well, when those
objects receive a message to update the array, just manually send
a bang to "arrayname_changed" when this happens.
