It’s been about 15 years on/off since I first looked at Monads. This weekend I finally sat down and really learned what they are, how they work. I found what looks like the seminal paper on them by Phil Wadler: https://page.mi.fu-berlin.de/scravy/realworldhaskell/materialien/the-essence...
I’m a pretty heavy Common Lisp guy, going on 30 years with it. I also did tons of SML and OCaml programming. But I only dipped my toe into Haskell a few times.
What I was looking for was a more in-depth understanding of Monads and how they work. I remember reading that Wadler paper many years ago, and I was intrigued by the conciseness of changing the interpreter to do different instrumentation. I was hoping to find a magic bullet like that for my Lisp code. And I noticed that Lisp almost never makes any mention of Monads. Surely there is a benefit that could be had…
Anyone else have Lisp experience using Monads? Did it offer some major enhancements for you?

Hi David, My lisp experience comes mostly from Scheme, but GNU Guix build tool/package manager has a monad abstraction: https://www.gnu.org/software/guix/manual/html_node/The-Store-Monad.html. They've even borrowed used >>= notation for bind. Best, Jack
