"Dynamic typing forces you to break things up into independent components much more aggressively."

I have the opposite experience with Haskell vs. Common Lisp or Python, but possibly because Haskell is purely functional, while CL and Python are imperative. I tend to write smaller functions in Haskell, where in CL and Python I create bigger functions with intermediate variables and bindings.

Another reason is probably absence of keyword arguments in Haskell which kind of forces you to make functions in Haskell to do only one thing and not too many things.

Yeah, I definitely think that the functional style coupled with immutability plays a huge factor.

However, I'm not referring to writing shorter functions in that comment, but rather about higher level components like namespaces.

Refactoring becomes painful when a particular piece of data is used in many parts of the application. When you change the shape of that data, then you have to make sure you update every place that uses it. This is where static typing can help ensure that you didn't miss anything in your refactoring.
