[...] On the other side there are downsides like what to do instead of reactive GUIs? GUI is a big part for a lot of applications. [...]
GUIs can be expressed in a *much* more direct and modular way in functional programming than imperative programming. See http://haskell.org/haskellwiki/TV and http://haskell.org/haskellwiki/Phooeyfor examples. No inversion of control is necessary. And not just for GUIs, but for reactive systems in general. See http://haskell.org/haskellwiki/Reactive and http://haskell.org/yampa/ . I'd cite easy & modular GUIs as a strong advantage of functional programming. Just to be clear, I mean really *functional* programming, not imperative programming in Haskell (IO). - Conal
