Yeah, you need to implement a custom equality operator.

class A {
    int member;
    override bool opEquals(const A rhs) {
         return this.member == rhs.member; // and other members 
that need to be equal
    }
}


The default opEquals sees if they are the same *instance* (same 
as `a is b`), and does not look at contents. You need to define 
that yourself.
