I'm not sure to understand which specific testcase you are
discussing, but for sure we don't want regressions. I agree that we
should assume a priori that the standard is right, but correcting the
make_pair should not lead to failures elsewhere (unless a proper
analysis establishes that the existing testcases are wrong)
Let's say it currently works by accident. What I believe is needed is
to implement the missing emplace function, and then operator and
others can be made to use it.
