The compiler tools in python/nondist/src/Compiler include Bill &
Greg's transformer code, a class-based AST (each node is a subclass of
the generic node), and a visitor framework for walking the AST.  

The APIs and organization are in a bit of flux; Mark Hammond suggested
some reorganization that I've not finished yet.  I may finish it up
this evening.

The transformer module does a good job of incuding line numbers, but
I've occasionally run into a node that didn't have a lineno
attribute when I expected it would.  I haven't taken the time to
figure out if my expection was unreasonable or if the transformer
should be fixed.

The compiler-sig might be a good place to discuss this further.  A
warning framework was one of my original goals for the SIG.  I imagine
we could convince Guido to move warnings + compiler tools into the
standard library if they end up being useful.
