No, no need to elaborate. What you described was exactly what I was
suggesting, exactly how numeric_cast used exceptions originally, and how
most programmers would expect to use inheritance with exceptions.
My question is that as this fine-grained approach was not favoured
before, should we now reconsider its use. In other words, should we
embrace such an approach more generally, eg for numeric_cast as well?
