Sebastian Gsänger a83d69e78f test pair-copyability on C++17 upwards (#1886) ... * test pair-copyability on C++17 upwards The stdlib falsely detects containers like M=std::map<T, U> as copyable, even when one of T and U is not copyable. Therefore we cannot rely on the stdlib dismissing std::pair<T, M> by itself, even on C++17. * fix is_copy_assignable bind_map used std::is_copy_assignable which suffers from the same problems as std::is_copy_constructible, therefore the same fix has been applied. * created tests for copyability		2019-10-31 12:38:24 +01:00
