main()
{
    alias int delegate( const int[] ) A;
    alias int delegate(       int[] ) B;

    A a;
    B b = cast(B) a; // OK

    B b2 = a; // Error: cannot implicitly convert expression (a) of type
              // int delegate(const(int[])) to int delegate(int[])
}

I think the cast is unnecessary, (b) should be allowed to point to a delegate
of type (A) as well.

I think you might have this around the wrong way...
