Yes it can be done in that way, but I want to avoid this (It will
complicate other things). In Generics.Defaults manual interfaces are easier
to maintain. Manual interfaces are more solid construction. They are more
resistant for improper use than regular ARC interfaces. You did not specify
any technical argument to discrediting manual interfaces implementation in
Generics.Defaults. Just a feeling :P. Your only technical argument has been
overthrown.
