Polymorphism resolved at runtime.

Given N different objects: O1...On each implementing the method f.
The implementation of f in Ox is fx.

If the source code invokes f on some object, the determination of the
type of the object (O1...On) and the implementation of f (f1...fn)
occurs at runtime instead of compile time.
