I have a different perspective: I'd prefer printing them as long as they are
synthesized (not part of the written source code).
While the example of combined template parameters might not be the best one
(and I agree that understanding them from existing contexts is often
sufficient), the conjunction of associated constraints for a class and the
corresponding constructor is probably less obvious. I think printing them would
make the situation clearer and help users avoid guessing. Moreover, this
approach would be consistent with what GCC does.
