Naming something in the terms of its implementation details (in this case recursion) is a classical WTF. On the other hand, it's by far not the only WTF in Unix. For instance, how often have you read "unlink" instead of "delete"? Or "directory" instead of "folder", pointing out that "directory" is the correct term because a directory is just a listing and does not "contain" the actual files. Of course these implementation details will never matter to anyone except under the rarest conditions. Thorsten -- http://mail.python.org/mailman/listinfo/python-list
