[heading Constraints]
* `T` must be a function type or a 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.
* Removes member `const` and/or `volatile` qualifiers from `T`, if present.
