I don't know how difficult it would be. The
warnings for unreachable clauses are there
because they are easy to emit when clauses
are discarded during optimisation and pattern
matching compilation. We have not really
looked at the problem of finding all unreachable
clauses; depending on how hard the problem
is, it might be more suitable to let Dialyzer do
