The table states that classes do not overload the assignment operator. However
this code compiles:

class A {
    int a;
    string b;
    float c;

    void opAssign(B b) {
       a = b.a;
    }
}

class B {
    int a;
}
void main()
{
    auto a = new A();
    a.a = 5;
    auto b = new B();
    b.a = 10;
    a = b;

    assert(a.a == 10);
}
