Why do std::pair and std::tuple behave differently when using std::scoped_allocator_adaptor'ed allocators for the containers?
std::pair fails:
std::vector<std::pair<std::string, std::string>,
std::scoped_allocator_adaptor<std::allocator<std::pair<std::string, std::string>>>> v;
v.push_back(std::make_pair( "one", "two" )); // <--- does not compile
while std::tuple works
std::vector<std::tuple<std::string, std::string>,
std::scoped_allocator_adaptor<std::allocator<std::tuple<std::string, std::string>>>> v2;
v2.push_back(std::make_tuple("one", "two")); // <- no problem
Is this related to the fact that std::tuple has uses_allocator while std_pair does not?
