Drop in dependor to see how it helps with DI.
Fix serializer initializer signature.
Inject dependencies with injector.
Make use of isolate in specs.

It requires particular naming discipline.
Less confusing specs with parsed vs. serialized wording.
Serializing collection is not rocket science.
Isolate does not quite like default dependencies.

Not a big deal now since I'm eager to experiment with dependor.
Add spec for serializers interaction.
Even more DSL and magic.
Little helper goes a long way.
