So far I've used F# form smaller projects, basically anywhere there's any un-trivial problem. Just the fact that the editor helps you write correct and concise code means that once you correct the mistakes that the editor (Ionide) higlights for you, things will just compile and work out of the box. Compared to Python, I'd assume that 1) I write a bit less code to solve the same problem in F# as I would in Python, 2) it takes a bit more time, but it is more fun, 3) once it compiles, there are seldom any bugs. So technically you trade some of programming speed for less time spent in debugging and writing test code. In the end, you are way faster and more productive. Especially once the code base starts getting bigger, the type system starts bringing in extra benefits. Major point is that detecting and correcting bugs in editor is faster than in compilation, and in compilation is better than at testing. So compared to Python, you get 2 orders of magnitude of better and faster development.
