Nothing if that's what you want.

The above question was inspired by certain posts to the monkey-thread
and the idea of stacked classes/methods, the proposal of module-
specific hacks and the idea of Module.import/rename (I looked at the
original library referenced by Pit Captain but didn't find the
extended one). Whether it's useful ... Currently I'm rather interested
in if it's possible.
