Jonathan Wakely e182158261 PR libstdc++/86751 default assignment operators for std::pair ... The solution for PR 77537 causes ambiguities due to the extra copy assignment operator taking a __nonesuch_no_braces parameter. By making the base class non-assignable we don't need the extra deleted overload in std::pair. The copy assignment operator will be implicitly deleted (and the move assignment operator not declared) as needed. Without the additional user-provided operator in std::pair the ambiguity is avoided.
