Google "walk directory". First hit is a Rosetta code page with
*recursive* walking implemented in various languages. So I guess it
does have this connotation. Regardless, os.walk has been in Python for
ages, and it's always been the go-to tool for recursive traversal.
walkdir's name suggests the same.

walkdir is a new module proposal. If its API is tedious and awkward,
it should probably be improved *now* while it's in development. Adding
yet another tool that implements part of its functionality, winning a
golf tournament along the way, isn't the solution, IMHO.
