IMO you are fighting a losing battle. We should implementnoexcept(auto) (possibly with some private __noexcept_auto__ spelling)and just use that in most places where we want a conditional noexcept.


That would be nice, but beyond my ability :-)

So until then we can either remove the exception specs entirely, or
make them correct.
