--- Comment #19 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Patrick Palka from comment #17) > Sounds related to PR92067, which requests that > __is_constructible(Incomplete) be a hard error. That request is far too simplistic and needs to be considered carefully. Consider the example in PR 104242, where overload resolution for the constructor has to consider the is_constructible constraints on std::any's constructor while the type is incomplete.
