No.  If you know a portable (as in "works on every compiler") way
to do that, we could talk.  If only some compilers understand it,
we'll probably end up worse off --- the ones that don't understand it
will still need things like these unreachable assignments, while the
ones that do understand will start warning about unreachable code.
