That was done, and implemented in libstdc++.

Maybe any remaining improvements should be left to PR c++/84920 and this one
closed? (The original report of inconsistent behaviour was just due to
forgetting -std=c++11, and the greedy rvalue overload is constrained now so the
output is similar for c++11 and c++98 anyway).
