Tres, I am a Python3 enthusiast and realist. I did not expect major adoption for about 3 years (more optimistic than the 5 years of some). If you are feeling pressured to 'move' to Python3, it is not from me. I am sure you will do so on your own, perhaps even with enthusiasm, when it will be good for *you* to do so. If someone wants to contribute while sticking to Python2, its easy. The tracker has perhaps 2000 open 2.x issues, hundreds with no responses. If more Python2 people worked on making 2.7 as bug-free as possible, the developers would be freer to make 3.2 as good as possible (which is what *I* want). The porting of numpy (which I suspect has gotten some urging) will not just benefit 'nemerical' computing. For instance, there cannot be a 3.x version of pygame until there is a 3.x version of numpy, its main Python dependency. (The C Simple Directmedia Llibrary it also wraps and builds upon does not care.) -- Terry Jan Reedy
