I'm the guy who's working a bit on the Smalltalk backend at the moment.
I'm very interested to see how your CLI backend progresses! Ideally, all
high-level backends (those based on the ootypesystem) should be able to
share some code and concepts. I haven't yet put much thought into this
while working on gensqueak, though. But if you see ways to share some
abstractions between gencli and gensqueak, you're very welcome to share
your ideas or refactor code. I will also watch what you are doing to
look for opportunities to unify things.
And just a hint, because no one mentioned it to you, yet: Many PyPy
developers hang out on the IRC #pypy channel on irc.freenode.net. It's a
good place to ask questions and get a sort of virtual office feeling
when you're working alone at home. ;)
