Still, I'm glad you are actually considering this a cross-language feature, and I will gladly retract my warning.

It might be pure python for Jython, but it's not for CPython. -- --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
