Yeah, and things like which which CLR version (3.5, 4.0),
implementation (MS, Mono), subset (Silverlight, MonoTouch, MonoDroid),
what host it's running under, etc. I was thinking of adding fields to
clr for that information anyway, but it can go here instead.

That ... yikes. It already does support some (not much) stuff using
-X:Python30, but that introduces a bunch of if statements and makes
the code quite messy. There are other ways to do it, but a clean break
in a new branch seems preferable to me. Plus there's the issue of the
reorganized stdlib, which I'm not really sure how to cleanly solve. So
my preference is to work in a different branch to 3k support. I'd like
to do some work after 2.7.3 is released, but I'm not sure I'll get to
