I'm sorry to hear that. I really like that proposal.

If there is interest, I can add std::constructor_from_tuple().

But maybe a function-object applier is better.


std::bind_front(std::applier(), std::constructor<T>());

std::applier()/std::function_application()/whatever is a function
object whose operator()() forwards to std::apply().
