We are currently discussing this issue in the Core Working group of the ISO
C++ committee. Currently there is not agreement that such an instantiation
should be disallowed. In particular, the case of an overloaded operator that
operates on enums is under consideration. In any case, there does not seem to
be a mechanism to suppress this warning at the moment.
