My thoughts here are taking a very primitive step - that is run the
JVM translation and look at the generated Java - then see what needs
to be modified so that I could use the generated Java parser from
Jython. At this stage I would be using PyPy exactly the way I use
ANTLR now - as a parser generator. There wouldn't be any need at all
for calling into Java code (as far as I can think of). I think if we
Jython developers get some experience with PyPY - we might be able to
help with the task of calling into Java from PyPy - since we know a
bit about that :)
