The following code should work and assert should pass.
On dmd 2.063.2 assert "Called `get' on null Nullable!Test" occurs instead
---
import std.typecons;
void main()
{
    struct Test{
        int a;
    }
    Nullable!Test a;
    Nullable!Test b;
    assert(a==b);
}
---

So, IMO Nullable!T needs opEquals implemented.
