But your classes do not represent the SET of integers and the SET of
modular integers. They represent the FIELDS (you include the operators
- and the class wouldn't be much use if they didn't.
The modular integers do NOT form a sub-field of the integers, which is
why you shouldn't use derivation to represent them.

Yes.
It is also true to say that even if there is /no/ competing proposal,
they would have to make a decision if they liked the proposed design.
My gut reaction is that you should be prepared for the LWG to be as
negative as the boost community.
