Well, you can test it easily youself can't you?

Btw, another solution is to change attr_reader, attr and attr_writer
to automatically define methods that will invoke callbacks.  If you
then in your code use accessors all the time you'll get notfied of
assignments pretty easy.  But: you won't see changes in Array and Hash
that way (you probably won't using instance variable callbacks
either).
