By this logic, switch statements should not have been invented
in the first place.  Clearly in C a need was felt for this syntactic
sugar.  Krste was merely pointing out that one can argue that
the same needs can motivate a similar extension for non-integral
types, of which there are a significantly larger number in C++
(that have equality operators) than in C.

I guess I don't feel particularly strongly about this issue;
I just felt the reasoning being used was flawed.
