Nonstatic typing brings down productivity very noticeably whenever I use it on anything beyond a small script. It introduces a large category of errors to make that static typing prevents; static typing makes the program more cohesive, structured, rigorous, and predictable. The only compelling reason for taking it away is laziness that'll hurt you in the long run, or if the problem/script is very small or trivial.
