> This is a mess, whatever programming language/paradigm you prefer. You will of course refactor the code. The point is - it's harder to make a quick and dirty prototype to see if it's better than the previous version (very common in game programming - you don't have strict requirements, you iterate quickly and check "is this fun yet"). And elegant functional code changes more than elegant imperative code for the same change in requirements, so the refactoring would be bigger for functional code (on the other hand the functional code is probably shorter).
