The good thing is that it's also a pattern that is highly amenable to syntactic sugar, simply because of how regular it is.
Actually, come to think of it, it is a particular instance of a more common pattern where you receive some state, and propagate it to most (usually, all) further calls that expect it. Scala implicit parameters and variables cover this in the most generic way.
