Thanks for mentioning this thread. Very interesting stuff. Apropos the implementability of an iterative listdir, I wonder if some variation of glob.iglob() would fit the bill. (Maybe it's too slow, though.) >I suspect if I thought about it much longer, only one would >really be needed, the other accommodated by the "topdown" parameter. Yeah, I think one only needs a post hook. The fact that it's a generator obviates need for a pre hook, since the yield returns control to the calling function right around where the pre-hook would run anyway. For the same reason, the post hook is needed only for the case topdown=True. Another useful callback would be one that replaced listdir in the generation of the current directory's contents. ~K -- http://mail.python.org/mailman/listinfo/python-list
