This is like saying it needed to support Python 2 before it could be
written on Python 2.

I assume you mean Python 3.  I think this (not trying to use 2to3) is
the right approach.

The code it generates is pretty simple, but if it can't generate
2&3-compatible code, then not worrying about 2to3 should make
generating code simpler.

The upgrade tests?  The bootstrap tests?  I would disable these to get started.
