That's a lot of work! I'm not aware of any tools that generate Python
source code from a parser tree. The Python bytecode is so high-level
that it is pretty easy to understand.
The parse tree generated by Python's builtin parser is really hard to
work with. So it definitely makes sense to use the transformer that
Greg & Bill wrote to get a decent abstract syntax. At that point, you
can either generate bytecode directly or write a new code generate
that generates source from the AST.
