            DeferringDict

is a dictionary that stores tuples of a callable and its arguments and will, on the first access, do the calls.

This is used below to defer the construction of instances in the class resolver to when they are actually used. This is important with interfaces, since they usually need the entire system up before they can sensibly be built.
