Like Clojure (which I have used a lot), Haskell development uses a repl (with really nice emacs support). For bottom up coding, I place a main function in every file with my test and experiments code; with an active repl in emacs it just takes a few seconds for the edit/run loop. In lower level code, I leave these main functions in place even though I am unlikely to need them once the code is working.

So, yes, Haskell and Clojure development has a similar flow.
