Sorry, somehow I hit the wrong button and GMail just sent off the email.
 What I wanted to say:

I'd be careful labeling Ruby as "functional".  The only "functional" about
Ruby is that with lambda you can have anonymous functions which you can
pass around and create higher order functions.  The core feature of
functional programming for me was always functions without side effects.
 And that is not part of Ruby.  Of course, you _can_ code lambdas without
side effects - but the language does not enforce this.

Kind regards

robert
