If we have a use for this in pre c++2a code, the libc++ convention would be to implement `__common_reference` that works most everywhere, and then have `common_reference` that only works > 17, but inherits from the ugly name. That might be difficult in this case, because users can extend `common_reference`. https://reviews.llvm.org/D49118 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
