Not to mention SFINAE, which would lead to a wall of text when multiple
specializations of a template exists (15 templates failed, each for 3
different reasons = 60 lines of error messages, none of which are
likely to be useful). And in such a case, no error messages are to be
printed if one match is found, right?
