No need for that; using quotes instead of braces will achieve the same
thing. The trouble comes of course if you want to substitute some
variables at definition time and others at runtime (or at the top level
of the subport but not inside the pre-fetch or other internal
brace-wrapped string). I guess you could use 'format' on the body.
