C-function-definer can't be defined as an ordinary macro, and is
probably a magic hook into the compiler's innards.

In Gwydion Dylan, what you want to do would be possible using
c-expr("&foo"), mainly because we're compiling via C.  Without knowing
what the FD compiler's hooks are, there is no way to know whether it's
possible or not there.
