I concur. We use Clojure, and the actual application logic is boring and simple. This is good because it is easy to navigate in code from any project (even from other teams).

Complexity is all at our common libraries. So most programmers don't even need to understand our abstractions, they just work. Of course, sometimes our abstractions are not enough so you need to get your hands dirty. However I would say it works well 99% of the time.
