Sorry for the mind shortcut. By that, I meant all sorts of problems where multiple state-bearing entities communicate via message passing - usually implemented via method calls in OO languages.
Well Clojure most definitely does support state-bearing entities that communicate using message passing (channels / agents / atoms...) and, while I confess I that I personally don't use them in _quite_ the same way that I use objects and method calls in an OO language, I find that programming in OO and functional languages is kind of converging towards the same point: functional programming in the small (immutable value objects that are worked on using pure functions) and OO in the large (state-bearing entities communicating using message passing).
