It would be intuitive if with would work like a local case expression.

Since we don't have local case expressions before we had with we had to
introduce a new top level function each time we wanted to perform a local
case analysis. With is basically a way to automatize this pattern but in
the end what you really want is having local case expressions. That with
isn't really the thing is already reflected by the need for inspect and
now inspect on steroids :-).

The good news is that we know how to implement local case expressions (or
smart ifs) and I have started this for pisigma. Yes, I know I got stuck on
this completeness proof but this is not essential for the implementation.
