As with many others here, I previously used Common Lisp for daily work, mostly at startups-- spanning 2005-2012 with spurts over 2015-2018 and some Erlang & Scheme in between. I had since moved mostly to Rust exclusively with some Python work last autumn and again starting last week with Clojure to be in the mix soon.
For something in between CL and Rust, I started looking at Carp but haven't committed. Somewhere under https://github.com/carp-lang/Carp it says "Carp borrows its looks from Clojure but the runtime semantics are much closer to those of ML or Rust."
I've met some of you at the Lisp 50 Birthday Party in Nashville. At the time, I was there from Seattle. After a brief tour of duty in San Francisco, I'm now in Vancouver and always open to meeting for coffee/tea/beer/cider.
