I looks like alayne is using 'purely functional' to mean Pure + Functional, but you are using it to mean Everything is an Expression / First-class functions, etc.. The functional paradigm.

Lisp is definitely a functional language. It's just not as pure as Haskell, which is the poster child for Maximally Pure FP, if not for the functional style.

Hence why I made the reference to Miranda.

We were already doing functional programming while Haskell was still using diapers.

Well, yes. Haskell is heavily inspired by Miranda. Haskell was just managed in a way that allowed it to become very popular.
