// *two* members for each implemented function: One which is public and

// to the interface, and represents the declaration of the function.
// Both of these come in to us. In the UI, the one we want to show is
// the public one. They come in in random order (they are stored in a
// hash table in the VM), so we don't know which one will come first.
//
// 2. When a superclass has a private member "m", and a subclass has its own
// private member with the same name "m", we will receive both of them.
// (They are scoped by different packages.) In this case, the first one
// the player sent us is the one from the subclass, and that is the one
// we want to display in the debugger.
//

// 2. It might be more complicated than that: Perhaps there is interface I,
// and class C1 implements I, but class C2 extends C1, and overrides
// one of the members of I that was already implemented by C1. In this
// case, the public declaration from C2 came first, but now we are seeing
