Kilion, In Haskell (a language that I love, just as Smalltalk) you have the REPL. The workflow is, while you are working on the project, you periodically load that file into the REPL and check. After that you compile. Haskell works with a strong type inference feature, however most Haskellers will say that the best practice is to annotate all functions. Also if you are on macOS you have: http://haskellformac.com/ which is awesome, really a great piece of software. There was even a project called Kronos that was essentially the same as IPython but with a Haskell kernel I don't know the status of that project as of today, I really never used it. just my 2c best Nacho
