[Push] pushtalk

[Lee Spector]

ccos,

Fairly intensive discussions are happening in private email, at least 
between 4 or 5 of us doing somewhat active Push development... I'm 
never sure when to divert these discussions to the list... And yes, 
we've unfortunately been getting quite a bit of spam -- every once in a 
while I nudge our sysadmins on this, and believe it or not I do think 
it has gotten better (and will get better at some point).

I'll be posting something substantive in the next couple of days, on 
Push 3.0, which a couple of us have been discussing and implementing 
recently. Perhaps that will be a good spark for more public 
conversations. As a quick sneak preview, the primary innovations in 
Push 3.0 are a new scheme for named variables/instructions that cuts 
down on the amount of code needed to use these, and a new "EXEC" stack 
that maintains the state of the interpreter (e.g. nested calls to DO*) 
explicitly. The EXEC stack was developed primarily to allow Push 
interpreters to be interruptable/re-entrant, but it turns out to make a 
bunch of other interesting things possible as well. C++ and Lisp 
versions will be made available. A lot of this has been spearheaded by 
Maarten Keijzer.

More soon!

  -Lee
