Although I'm not yet retired, I have been thinking about something similar. When I was younger, I loved learning new languages. Now I find I'm less able to learn so quickly, and I'm more interested in getting things done. I'm interested in building things that are reliable and will last, so Haskell has been interesting to me. However, there is something about Common Lisp and Racket that keeps drawing me back, even though I tend to favor static typing. (Maybe Typed Racket is the answer?) My everyday language right now is Python, but I'm looking for something that feels more solid.
