          Issue ID: 24893
           Summary: Member functions passed by AliasTemplateParameter are
                    not callable
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Keywords: rejects-valid
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: b2.temp at gmx.com

The following program should compile successfully:

```
class A
{
    void f(){}
}

class B : A
{
    override void f()
    {
        alias Fun = A.f;
        test!(Fun)(this);
        // same errors
        test!(A.f)(this);
        test!(super.f)(this);
    }
}

void test(alias Fun)(A a)
{
    Fun(a);
    a.Fun();
}

void main()
{
    (new B).f();
} 
```

instead we got the following errors
