I think there's another class of "clever/amazing" code that wraps up esoteric language features in easy to use APIs/libraries. So while the actual implementation can be quite hard to follow/understand (especially for novices) consuming the service is incredibly easy and makes an otherwise arduous task simple and requiring far less code. I've found myself writing these kind of modules often over the years. They often use RTTI/reflection and generics and make a task declarative rather than procedural. A couple that spring to mind are a messaging/subscription framework in C++ (heavy use of templates) and a reporting API in C# (lots of reflection). Always do my best to make the implementation comprehensible but there's only so much you can do when they require a deep understanding of the language.
