This talk might be of interest Stuart Sierra - Components Just Enough Structure https://www.youtube.com/watch?v=13cmHf_kt-Q https://www.youtube.com/watch?v=13cmHf_kt-Q - it is a tiny clojure framework but the ideas should be thought provoking, although granted with OO aligned type system not completely adaptable. In this example Customer could possibly just be a data-bucket/map/hashtable/Dictionary, Im not entirely sure how I'd handle reporting though as the example has put me back in OO mode, but a customer report (which knows how to organize data about a customer) shouldnt be part of customer entity (used loosely) in my opinion.
