It's funny, because most of the larger OOP projects I worked on were large because of class bloat, not because of business concerns. For example, the C# app I used to work on was a more or less simple CRUD app. We had a ORM that served up objects to a Silverlight UI. So if we wanted to display information about a person on the UI we normally had to modify around 5 classes in 5 files. We had the following layers
ORM - 1.4MB of generated C# for interfacing with the 200 or so SQL tables we had DTO - Data Transfer Object, where used "normal" C# objects to abstract the ORM. This is where we had the "Person" object API - A web service that served up DTOs over HTTP Data Model - Processed views of DTOs formatted in a way that was easily viewable by the UI View Model - UI classes that would take data from a Data Model and emit UI controls. All of that ceremony....that is replaced by one thing in Clojure...data. Hashmaps and vectors replace all the junk you see above. So that's where I often assert "Yes, you may have 1 million lines of Java code....but that would only be ~10,000 lines of Clojure." With proper application of data driven systems (data that configures pipelines and writes code) you can easily get a 100:1 ratio of Java to Clojure code.
