The ``compiler.ast`` module makes parsing Python source-code and AST
manipulation relatively painless and it's straight-forward to implement
a transformer class.
However, I find that the ``compiler.pycodegen`` module imposes a hard
limit on the length of functions since it calculates jump points in a
recursion.
I'm using this module to compile an XML dynamic template into Python
code (akin to "Mako") and functions may grow to a rather large size.
Now it seems that the ``parser`` module, which parses source code into
``parser.st`` trees does not have the same limitations, however, I could
not find a transformer class compatible with its tree structure.
What's the recommended way of working with the AST tree from the
``parser`` module?
