"Yes" and "I guess".  =)  I can see the filename to check a module
useful for stuff like PyChecker.  But for a string of code, I don't
think it would be that critical; if you provide a way to get the AST
for a code object you can just pass the string to compile() and then
get the AST from there.

Yep, import path -> filename path would be cool.
