Ah, you mean I should use (.eval (pmacro-expand '(.sym ...)))!
But that's frowned upon (pmacros.scm) (supposedly because you
break through the CGEN description interface into scheme and
nasty things not accounted for can happen):

 ; .eval is an experiment.  Ports that consider themselves to be of beta
 ; quality or better don't use it.

Besides, I *expected* implicit re-lookup of a symbol built-up
from (.sym ...).  I think it comes naturally: what happens to
abc should happen to the expansion of (.sym a b c).  If people
don't want re-lookup, may there can be added explicit deferring,
by, say, (quote ...) ;-)
