[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.
|
||
|
|
* Removes C-style variadics (`...`) from the signature of `T`, if present.
