S-expressions are consistent, pleasant little creatures. I think they're underrated.
I mostly see them in Lisp family languages, but was curious: are there non-Lisps that use S-expression syntax?
Here are some that seemed mature, interesting, or active.

A ☠ means that the most recent commit, when I wrote this, was more than 12 months in the past.
I omitted Clojure and Hy since they consider themselves to be Lisps. They're included in awesome Lisp languages.
If I'm missing an interesting S-expression language, let me
know at m.sexp@ndrix.org
