There's not much shared between the old and new compilers, so I don't
think hooking the asmified version of old compiler up to antlr would
help much in translating newcompiler to Java.  It sounds like Tobias
has a significant portion of hooking the newcompiler up to antlr done
as well, and he's actually going to get some serious time to work on
this leading up to PyCon.  He could speak to that better than I can
though.

I started looking at translating pyasm.py into Java this weekend, and
it doesn't seem like it'll be too difficult.  Since it's all based on
the asm visitor stuff, it isn't doing much magic that isn't directly
translatable to Java.  I'm starting to get a little swamped at work,
so I don't think I'll be able to put in any significant time on it
before PyCon.  You're more than welcome to pick up that effort.
Tobias seemed interested in getting some help there too.

Ah, thanks Charlie, I was on the fence about this part anyway.  I'll skip it.

I'm actually going to get some face to face time with Tobias and Jim
next week.  I think it would still be valuable to get the antlr parser
hooked up in a real Jython (even if it is with the old compiler), so
I'll go ahead with that.  It can act as a scaffold for new work I
think.

Cool, I'll take a look at that soon.

Sounds good, I'll check with Tobias on that.
