Did you know that you can actually abuse decorators to do this with existing syntax? Check out this collection of evil uses of decorators: https://github.com/Rosuav/Decorators/blob/master/evil.py I call them "evil" because they're potentially VERY confusing, but they're not necessarily bad. The monkeypatch decorator does basically what you're doing here, but with this syntax: @monkeypatch class A: x = 5 def foo(self): pass def bar(self): pass It's a little bit magical, in that it looks up the original class using globals(); this is partly deliberate, as it means you can't accidentally monkey-patch something from the built-ins, which will either fail, or (far worse) succeed and confuse everyone.
