Comment(by simonpj):
I'm suggesting this:
* everythig exactly as now except that (3) only applies to arguments
whose type are `ForceSpecConstr`'d.
In the #4448 code you give, that'd mean you'd have to `ForceSpecConstr`
the Left/Right type. Or, maybe there could be a different annotation for
that, meaning "if you see a function applied to me, ignore the "must be
scrutinised" test.
