True, but still, it's nice having the functionality there.

I agree that in a true Pythonic sense, having a revamped os.path.walk
API which returns an iteratable object (probably a generator) makes a
lot more sense, as someone else pointed out; it seems a lot more elegant
to write

	for file in walk(dir):
	    ...

rather than

	walk(dir, lambda f: ...)
