I'm totally blank (what "this"?)  I generally want to map a
pmacro on a list defined as a pmacro, generating calls to other
pmacros.  How can I do that without re-lookup?

(define-pmacro x (a b c))
(define-pmacro (do-a y) (+ y 1))
(define-pmacro (do-b y) (- y 1))
(define-pmacro '(do-c y) (* y 2))
(pmacro-expand '(.map (.pmacro (z) ((.sym code- z) ((.sym do- z) w))) x))
=> ((code-a (+ w 1)) (code-b (- w 1)) (code-c (* w 2)))

Hmm, maybe that didn't come out clear.  Tell me if you feel you
need something better.
