Regarding your claim about FP languages:
[FP languages] mostly have a strong element of type safety. This is usually seen as a good thing [...], but there is a downside. It tends to also enforce a bottom-up approach to coding! It is very difficult to write top-down code where, in the early stages, many elements of the solution one is seeking are unknown.
Are you extrapolating too much from personal experience? Because you find top-down coding in FP languages difficult doesn't mean that it is in general. For instance, I work almost exclusively top down when I code in Haskell, and it seems effortless. Could there be another explanation for your experience?
