I have to agree with Christian that inspect.py is full of hacks and heuristics that would be fine in a module that's part of a user's app or even in a library, but stand out as brittle or outright unreliable in a stdlib module. Basically, you can't trust that inspect.py will work. I've seen various occasions (sorry, can't remember details) where some function in it outright crashed when given a slightly unusual (but not unreasonable) argument. It might be a nice project for a new contributor to improve this situation. -- --Guido van Rossum (python.org/~guido) _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
