So far I’ve gotten through Chapter 9. Paulson really did an excellent job with this book, and I’ve had the a-ha! moment in my head quite a few times so far. SML seems to change the way that you think about programming and problem solving in general. I don’t have much else to say since I’m a functional programming newb, but I would recommend every software developer to try out SML.
I was inspired by this book, so I decided to implement some standard Unix utilities in SML. It’s just a toy project, so I don’t expect to implement too many programs. If you’re interested, the code is on Gitlab.
