In retrospect, for me many of the problems would have been fixed it they'd wrapped everything in one release, like gcc with the -std flag.

Then once someone had (say) python 2. 6 I'd know they also have python 3.2, and I wouldn't have to figure out that name of the executable to call, it would just be python, with (perhaps) either a command line option or a comment at the top of the file.
