How has The Little MLer aged?

I’ve been looking around for books about ML and found The Little MLer. It was published in 1998 so I was wondering if it’s still a good resource.

What was your experience with it? Any thoughts?

It only covers the parts of OCaml that are also in SML and the last chapter can be a bit hard to follow with OCaml due to some subtle differences between the module systems, but it’s still valid. It was my introduction to OCaml, so it surely worked for me!

I also uploaded all the code from the book on this repo, in case anybody needed help with the last chapter.
