I appreciate that you wrote that you "feel" more productive with python. I 100% agree with this feeling at most scales of code size, and the feeling matches reality at the small scale. However, I've found that this feeling of productivity doesn't match reality in the large. I use Haskell for programming in the large despite this feeling of unproductivity, because in fact, I am way more productive.
Just to clarify, I agree that Haskell can be more productive than Python, I was talking about productivity of Python (or, for that matter, Lisp) compared to C-like languages of the era. But with Haskell's type inference, the Python's advantage is lost (if we forget, for a moment, extremely well-designed Python's standard library with focus on convenience).
