Yes, sorry. The effort to extract a readable, fairly minimal example, gone wrong.

AL == AbstractLoader
ALFactory == AbstractLoaderFactory

Of course. Silly omission.

True enough, and either is fine. Use of super() is habit, encouraged by following some guidelines <http://wiki.osafoundation.org/bin/view/Projects/UsingSuper <http://wiki.osafoundation.org/bin/view/Projects/UsingSuper> >, with future subclassing in mind.
