note: you can have cuircular implementation references just not cuircular
interface references.

so sometimes some extra typecasts will be needed if classes need to have
referenes to each other but its not usually any worse than that.

converting between OOP languages will always be hard because they all use
different object models and most code is designed around the object model of
the language in use.
