Right, but of course it is recursively undecidable whether an
expression is constant, so you don't really mean what you say.
What you mean is that warnings could be given in a few cases,
e.g. where the expression is a literal, but going beyond this is a
waste of time, which will not be helpful in practice, no one
is going to watch p-p anyway.
