Yes. In particular, consider if A is "Etats Unis" and B is "France" and C is "United States".

It's possible that the user supplied equality operator will give true for A=C.
But an alphabetization on the representation will yield A < B < C.

The same argument, with some changes, applies to hashing functions. Received on Sun Aug 29 2004 - 17:24:41 CDT
