Passing args with nested pmacros

[Will Newton]

Hi all,

I'm trying to simplify some cgen macros and I would like to be able to
to map a pmacro over a list, but also pass the pmacro some other
arguments. e.g.

(define-pmacro (sub-macro item arg) ...)

(define-pmacro (top-level top-level-arg)
  (.map (.pmacro (list-item) (sub-macro list-item top-level-arg))))

But this doesn't look like it's possible because .pmacro's don't do
lexical scoping. Is there any way to do what I want?

Thanks,
