Huh, that is an interesting use!  I notice that he enables that for both GCC AND Clang, but probably doesn't notice because he disables Wpragma as well.  So this change would change the legality of his program (potentially) for Clang (though, we ALREADY would have broken any SFINAE/concepts uses because of the SFINAE change in 16), but only to be what GCC gives him?  I think we can be ok with that?
