[Python-ideas] Possible Enhancement to py Launcher - set default

[Paul Moore]

I don't think so. As an example, what registry keys would Anaconda
write to say that Release 5.2.1.7 is a pre-release version? Or would
the py launcher have to parse the version looking for rc/a/b/... tags?
And distributions would have to agree on how they record pre-release
version numbers?
