No, not really. My "evil hack" comment was meant to point out that even though the function would work, it wasn't great to use in "production" code, and further, that although python easily permits things like counting call stack depth, the better way to count the level of recursion in a recursive function call was to, well, count it. :-) -- http://mail.python.org/mailman/listinfo/python-list
