Thanks! I’m using Emacs and Merlin, with the utop extension. It works when I run it by itself, but if I try “dune utop” it has some formatting error in the buffer…

Yes, I staying with Emacs for now, but I will keep an eye on it.

As a second book, On Lisp is nice, and also available for free. It’s a deep dive on macros!

Have you played with Erlang? It has a different view on how to do error handling and concurrency.

On a similar vein there is “Build your own Redis”, I may actually try that one in Common Lisp!

I guess most people don’t take it home with them.
