[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.
|
|
* Adds a member `const` qualifier to `T`, if not already present.
