But if I had to do it over again, I wouldn't have added walk() in the current form. I often find it harder to fit a particular program's needs in the API offered by walk() than it is to reimplement the walk myself.

I do not much use os.path.walk' myself. It is so simple to write a small walking loop with a stack of unseen directories, and in practice, there is a wide range of ways and reasons to walk a directory hierarchy, some of which do not fit nicely in the current os.path.walk' specifications.

That's why I'm concerned about adding to it.

The addition of generators to Python also changed the picture somewhat, in this area. It is often convenient to use a generator for a particular walk.
