[heading Constraints]
* `T` must be one of the following:
* function type
* function pointer type
* function reference type
* member function pointer type
* If `T` is a pointer, it may not be cv/ref qualified
[heading Behavior]
* A substitution failure occurs if the constraints are violated.
* Adds a `noexcept` specifier to `T`, if not already present.
