Implementation of invoke_result<t_FN, t_ARGTYPE>. This specialization is instantiated in C++11 and later when t_FN is a pointer-to-member-object type, t_ARGTYPE is a specialization of bsl::reference_wrapper, and the INVOKE(fn, arg) expression is well-formed given fn is an object of the specified t_FN type and arg is an object of the specified t_ARGTYPE type. The INVOKE(fn, arg) expression in this case is arg.get().*fn.

myDeclval | Return a reference to the specified t_SOME_TYPE template parameter type; if t_SOME_TYPE is an rvalue, then the returned reference is an rvalue reference. This function is declared but not defined and is intended to be called in an unevaluated context. Because there is no definition, the available constructors for t_SOME_TYPE are irrelevant. |
