Then fix your debugger. ;-) As I recall, you're a proponent of fixing what's broken rather than creating workarounds. (I also recall many discussions regarding failed sandboxes because of Python's nearly infinite capacity for introspection. Maybe closures are the path to a true sandbox.) Globals, persistent locals, closures, statics, class variables, instance variables, etc. are all just different ways to hide state. IMO, we don't need another one. _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/LOB2FKM5XV3Y3TGQB532G7F2RF4JOHLN/ Code of Conduct: http://python.org/psf/codeofconduct/
