These are the reasons I advise using Haskell for startups. If you make everything validated (or much of it) at compile time you can move very quickly. There's also the feeling of the code writing itself. In some places you can literally put in different functions until it typechecks which is great for exploring a problem domain. In the future I hope to be able to recommend Idris as well.
