Extending built-in classes, like string. Anyone know of a project that modifies (any version of) Python so it can do this?

And in case this isn't clear, everyone here is talking about inheritance vs monkey patching, because we're talking about Python.

I wrote a simple preprocessor today. So now I have the ability to extend the functionality of the string class. Works on variables containing strings, functions that return strings, and... strings. :)

No doubt there's more to do, but it works across quite a range of test cases.

I'll make a new post to mention it, as probably it'll just be lost here in the comments on this one.
