> "you can do immutable/functional programming with regular ol' Python" One cannot easily and safely do functional programming in Python due it's imperative semantics. For example variables are captured as mutable references and even a list comprehension will mutate its bindings. If you want to do serious functional programming, use Clojure, Haskell and/or OCaml. Edit: to the downvoters, it's about using the right tool for the job.
