This is a bit out of yacc.py . So in Python, the IsNot operator is written "not id()". This directly violates their first claim, and pre-dates it, and is public, and as far as I know, renders it invalid. But I think they clearly showed their strategy here. Just patent anything small that would be required to maintain compatability. I think Mono is screwed for this reason. Gnome should have bet on a Python tool chain.
Our patent system is basically out of control. But there are ways to fight back. For every nuclear weapon requiring a expensive reactor, there's a biological one that can be grown in your backyard. I won't give it away here though. :>

This function is written # in a way that guarantees uniqueness of the generated goto sets # (i.e. the same goto set will never be returned as two different Python # objects). With uniqueness, we can later do fast set comparisons using # id(obj) instead of element-wise comparison. halvar () gmx de wrote:
