Well, for the record, buildq already has something corresponding to the
comma in a backquoted expression -- the variables in the list (first
argument) are substituted into the otherwise quoted expression. So
buildq([x], 1 + x) is analogous to `(1 + ,x). I suppose it could be
argued that we don't need unquote since we already have buildq.
