GVW writes: I agree on all counts except garbage collection --- I'm half-way through the second day of the Python class I teach at Los Alamos (the people who are funding the Python tool design competition), and it's come up a couple of times. People want to be able to prototype meshes, throw callbacks around without worrying about circularity, and some other things that I don't really understand yet. There's also a couple of smart guys in the class who are wondering about CPython vs. JPython ("So this'll be safe in one version of the language, but not in the other?"), and about marketing ("Help me win a feature comparison against Java in my group..."). There's also been questions about tighter integration of NumPy (e.g. overloading operators rather than calling 'greater()' to do comparison), but I think that's a separate discussion... My $0.02, Greg
