* Overload of _rename that takes an associative array * translate as a template parameter, where the keys are * either the names or indices of the members to be changed * and the new names are the corresponding values. * Every key in translate must be the name of a member of the * tuple. * The same rules for empty strings apply as for the variadic * template overload of _rename.
