I don't disagree with that in general, but strictly rejecting strings and other non-integer values would alleviate the problem for a majority of cases; i.e. would solve the 90% problem. What I strongly disagree on is that I should be happy with coercion, and the almost religious resistance against (non-overridable) strict scalar typing.
