I've been coming up to speed with Janet, which is quite lovely. Depending on what kind of work you're doing, especially if you're looking to do work with it, Julia might be worth some time. It takes a rather long time to really grok the magic of it, but I've found multiple dispatch to be as significantly influential to problem solving as FP and immutable data concepts. It's weird, it takes time to become comfortable with it. Depending on your use case, Guile Scheme has made incredible performance strides. Wingolog has a fantastic blog detailing some of those adventurous commits. It's nearly intimidating seeing his skill with Scheme. Edit: nearly forgot! https://github.com/lokke-org/lokke https://github.com/lokke-org/lokke Lokke is clojure on guile. Pretty cool, haven't actually used it yet, so ymmv
