| Implementation of `invoke_result<t_FN, t_ARGTYPES...>`. This specialization is instantiated in C++11 and later when `t_FN` is neither a pointer‐to‐function, pointer‐to‐member‐function, nor pointer‐to‐member‐object type, and the `INVOKE(fn, args...)` expression is well‐formed given `fn` is an object of the specified `t_FN` type and `args...` are objects of the specified `t_ARGTYPES...` types. The `INVOKE(fn, args...)` expression in this case is `fn(args...)`.
