== Description

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`.
