This is by the way how everything with clojure is developed (If you use the repl/figwheel/shadowcljs/combination of all of these) !

Instant changes and no reload/recompiles.

Clojure is the only language I've been excited about since the early days of Ruby. I wish so much that it would catch on, and especially I wish it would supplant Javascript.

Clojure is such a sane, elegant, and expressive language. Elixir is pretty ok, especially on BEAM, but it looks like Perl compared to Clojure. It's just a tragedy that for the best career options one must basically choose between Python or Javascript. (js because that's what everyone uses for front end, and python because that's what's apparently eating the world via AI, ML, etc.). To be nice to Python, it's a very practical language. It just is completely inelegant compared to Ruby and especially Clojure (and even Elixir).

Every couple of years I tell myself, "I'm going to do my next project in Clojure; reality be damned!". But always I give up and fall in line.

Try Hy (http://hylang.org) for a Clojure-ish Python.

Without maps or persistent data structures, it won't feel Clojure-ish beyond simple examples. But a lisp on top of the Python ecosystem is an exciting project.

Without maps? What's wrong with a Python dict?

This is by the way how everything with Lisp is developed.

I suggest some reading about Interlisp-D, Lisp Machines and Common Lisp commercial IDEs.

Everything with Lisp is developed is a bit of a stretch. This isn't the way e.g. Racket is usually developed IIRC.

Racket is a Scheme variant and Dr Scheme, now Dr Racket, is a kind of interactive development environment similar to the above ones.

However when I talk about Lisp I seldom think of Scheme, due to their differences, in spite of the common parentheses.

I've barely used Dr Racket and even then it's been years so I might be misremembering, but I don't think it comes with any hot swap capabilities (the main point of this demo) out of the box, even though it had a REPL.

Yeah I was about to say, I can't think of any Scheme implementations or descendents with robust support for hot swapping.

The current transition to Chez Scheme might allow this in the future.
