I think the idea of the return types is more general than just for
min_result and max_result. I would prefer to see a type generator for type
promotion and demotion.
This is generally useful in other scenarios such as matrix return types etc.

May I suggest promote_type<A,B> and demote_type<A,B> as the names for the
appropriate type generators?
