We're starting to use potemkin at Prismatic, and the part we've found most useful which Zach didn't mention in his post are the smart types. Especially definterface+, which is like a love child of defprotocol and definterface: - Same syntax as defprotocol, and defines functions in your namespace that wrap the interface functions (without extend-protocol support, obviously) - Allows for primitive arguments and return values (like clojure.core/definterface), which are propagated to the wrapper functions for maximal performance - Doesn't re-evaluate if the body has not changed, which can make repl development less painful (especially when used with its defrecord+ counterpart).
