Hello,
I've been playing with closures and subs but I have a little bit of 
trouble with those.
I'm a bit confused by all different flavours of syntax, I've been trying 
to read and understand all documents concerning this subject, the most 
useful was reading the test scripts. However, that is PASM, and I like 
PIR better :-).

A general question is: what syntax should one use in what context?
(I understand that PCC should be used whenever one wants to interact 
with other languages. Also, calling functions can be done in many ways)

A more specific question is this:
I'm trying to create a closure, and I think I've implemented this code 
(it's lua code, but I'm not sure if it's 100% correct,
anyway, I'm trying to get a feeling for how one should translate this). 
So, actually I have 2 questions;

(1): did I translate the function below correctly (I think the Lua 
syntax won't be a problem, it's quite straightforward).
(2): what is causing my strange result (see below).

       # foo(q)
       .arg q
       $P0()
Try this instead:
         $P0(q)
