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:<div class=""><br class=""></div><div class=""><a href="https://page.mi.fu-berlin.de/scravy/realworldhaskell/materialien/the-essence-of-functional-programming.pdf" class="">https://page.mi.fu-berlin.de/scravy/realworldhaskell/materialien/the-essence-of-functional-programming.pdf</a></div><div class=""><br class=""></div><div class="">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.</div><div class=""><br class=""></div><div class="">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…</div><div class=""><br class=""></div><div class="">Anyone else have Lisp experience using Monads? Did it offer some major enhancements for you?</div><div class=""><br class=""></div><div class="">- DM</div></div></body></html>
