I'm not exactly defending monkeypatching. It's better than nothing, and if used judiciously it doesn't have to be especially dangerous. All the rope you need and all that...

And, what you're describing is very cool on its own merits.

What I want to know is whether this will get you out of the same messes that monkeypatching can. If it will, but in a more controlled way, then that's really awesome.
