A type alias to an enum type cannot be used to qualify the constructors:
A type alias to a tuple-struct or unit-struct cannot be used to qualify that type's constructor:

```rust
enum E { A }
type F = E;
let _: F = E::A; // OK
// let _: F = F::A; // Doesn't work
```rust,edition2018,compile_fail
struct MyStruct(u32);

use MyStruct as UseAlias;
type TypeAlias = MyStruct;

let _ = UseAlias(5); // OK
let _ = TypeAlias(5); // Doesn't work
```
