This is rather tangential, and sorry to hijack your message to get on my soapbox, but I and many others who program in Haskell and a dynamic language (Python in my case) find that Haskell code we've written is far easier to come back to than code we've written in the dynamic language.

Ya I tend to agree actually, but in the real world I keep getting scolded for being too "functional". I think that it might come down to the easy != simple argument, which the whole CS industry is still grappling with in other areas as well.
