It seems to me that all this version range talk relates pretty directly to PEP 386.
The Python version numbers themselves are the simplest type of "Normalized Version"s, and since comparisons of "NormalizedVersion"s are defined in PEP 386, and that's really all we're talking about here, shouldn't this really just follow and reference that document?
Sure we might like some sugar to make expressing ranges simpler, but shouldn't the explicit meanings of any rules be stated in terms of Normalized Version comparisons?
