Hi!
I defined an interface:
interface Medoid {
float distance( Medoid other );
uint id() const @property;
}
and a class implementing that interface:
class Item : Medoid {
float distance( Item i ) {...}
uint id() const @property {...}
}
The compiler says:
Error: class Item inte

The two signatures need to be the same. I think this is true of
most OOP languages. Have them both be:
float distance( Medoid other );
The distance function is implementation dependend and can only be
computed between two objects of the same class (in this example
the class is Item).
My goal is to write a module for a k-medoids clustering
algorithm. The class MedoidClassification shall be able to
partition a list of objects

What would be a good way to implement this?
Did you tried to use introspection?
You can do something like this:
interface Medoid(T) {
float distance( T other );
uint id() const @property;
}
class Item : Medoid!(Item) {
float distance( Item m ) { return 0.;}
uint id() const @property { return 1; }
}
class MedoidClassification {
this(T:Medoid!T)(T[] list)

Just don't put it in the interface. Leave it in the individual
classes with the strict
