If you're asking my opinion, then "yes".  It seems the $1...$n
variables form a very special case in variable creation, use, and
scope.  It would make sense to me to have the $(call) operation hide
from nested scopes the $n variables it creates.  How this hiding is
implemented is best decided by you.
