Lisps

I like people with lisps. My ears enjoy hearing their voices!

Indeed, a few dialects of Lisp make it an error to call car and cdr on nil. Most Lisps behave like Emacs Lisp in this regard […]

When I talk about Lisp, the advice will apply across all the major Lisps (including Clojure, Scheme, and Common Lisp).

Lisps have been called functional programming languages, but Clojure embraces that more deeply than do Common Lisp or Scheme.

For compatibility with older LISPs, all symbols have property lists, with property names and values arranged in even-odd pairs.
