It’s in the declaration of the ivar, I mean ‘stored property’, 
backgroundSession, so there is an instance.

But I just realized that Rick forgot the “lazy” keyword. Without that, I think 
the block executes at initialization time, not when the property is first 
accessed. (Either way, it would still make sense for ‘self’ to be available.)
