Hi,
I think that the documentation is pretty clear ("[if topdown=False] ... the
directories in dirnames have already been generated by the time dirnames itself
is generated"). And such behaviour is what one would expect, since it is the
result of the simplest implementation (listdir(), yield <subdir>, yield
<subdir>, yeild <subdir>, yeild <dir>).
I don't think that the implementation will be changed, since it is pretty to do
listdir() yourself if needed, and it would make the function slower for the
common use case.
Improving the documentation is always possible, what sentence would you see
added (what would make the behaviour clearer to you?) ?
