           Summary: Using enum of struct (containing another enum) before
                    its declaration fails

//////// test.d ////////
struct S
{
    enum E
    {
        e1 = 0,
    }
    E e;
    enum S s1 = S(E.e1);
}

SE se;

enum SE
{
    e1 = S.s1
}
////////////////////////

test.d(8,15): Error: cannot implicitly convert expression `S(E.e1)` of type `S`
to `int`

If the declaration of `SE` and the use `SE se;` are reordered, the problem goes
away.
