 * This gets really nasty now that constructors can invoke operations on us.

The error handling currently bails if the thing we just instantiated should be discarded. This could happen if (for instance), a constructor did a bindVolatileInstance of its own class to an instance, or somehow triggered an injection of itself with a different plan (an injection of itself with the same plan would lead to an infinite recursion, so it's not really our problem).
