It's not inconceivable that PyPy could grow into some of what I'm talking about, although there's so much pushback from the Python community that I doubt it. However, as far as I can tell, PyPy doesn't have a parser generator written as part of normal Python code; it has a hand rolled recursive descent parser and a hand rolled lexer, which is not quite the same thing.
