opEquals

[deed]

interface I
{
    bool opEquals(I i);
}

class C : I
{
    bool opEquals(I i)
    {
        return true;
    }
}
void main()
{
    I i1 = new C;
    I i2 = new C;
    assert(i1 == i2);  // Assertino failure
    assert(i1 != i2);  // Passes, although it's the opposite of 
what I want..
}

What's missing?
