Refering to N2800 all container requirements tables (including those for associative containers) provide useful member function overloads accepting std::initializer_list as argument, the only exception is Table 87. There seems to be no reason for not providing them, because 21.5 [unord] is already initializer_list-aware. For the sake of library interface consistency and user-expectations corresponding overloads should be added to the table requirements of unordered containers as well.
