Looks good.  Also reminds me of an extension to @ or @@ that I was going 
to ask about.  Namely, so as to allow lookups within the environment of 
a closure.

So, for example, with

(define (xxx . args)
   (define (internal-proc x y z)
     ...)
   ...)

one could reference the procedure for "internal-proc" as

   (@@ (MODULE NAME) xxx internal-proc)

Probably only useful for debugging - i.e. it would make it possible to 
set a breakpoint on internal-proc - and other kinds of introspection, 
but what do you think?

(I also realize that what I've suggested doesn't really fit @/@@, 
because @/@@ currently return variables, and internal-proc in this case 
only exists as an ILOC.  But perhaps you can see a way round this?)

Regards,
	Neil
