Your library is very nice. But - it suffers from the

a "lazy" IO list, and we all know what grief that can
lead to.

This is little different from the approach taken by Python's os.walk, which lazily yields the contents of a directory tree as it traverses it. I'm a little unclear on why one appears good in your eyes, while the other is not, beyond perhaps the depth/breadth knob and differences in amount of documentation. Maybe you could expand on that a bit?
