There are a lot of strategies to deal with the coupling of reuse. I find that using pure functions makes it easy to split off responsibilities after the fact and add multiple entry points (the hard thing becomes naming those functions). Eventually a new 'essence' of the abstraction will show itself and inspire a larger refactor. That's something I really miss when doing java.
Also, I feel that the reusable clojure code is always doing more work than corresponding java code, so my frustration in refactoring is much greater with java and its IDEs. The refactorings are always superficial compared to what I'm trying to express, and in clojure I can work with data contracts easily. I often end up writing a new version of the reusable abstraction, writing adapters (just data transformations) from the old to the new, then gutting the old implementation, then hopefully gutting the adapters over time. Clojure's data focus makes this easy.
