All,
Please read Clinton's reply - especially the part
about being blocked from the list for about a year.

Cheers,

Clinton,
What kind of knowledge are you looking for?
How would you want to rewrite the Parrot BASIC compiler? in C or in PIR?
Depending on the level of knowledge you need, I could help you (I know a
bit about parsers, I think :-)

(I've been trying a lot to implement a Lua compiler (version 5), but I'm
seriously stuck on generating code for assignments (it's not as simple
as it seems, but then again, I may be thinking in the wrong direction;
for that I need either an implementation example (doesn't do Perl do
multiple assignments? (i.e. a, b, c = c, b, a) , but that's another story).)

Anyway, could you describe what you would need? Maybe I can help.
regards,
klaas-jan

I've no idea, but Python does.

a, b, c = c, b, a

<=>
(a, b, c) = (c, b, a)

What's the matter exactly (maybe we should continue that off-list)?
