I've read (part of) this book and used it to implement a toy compiler. It helped me a lot in getting a better understanding of Haskell and other functional languages. This is really an amazing book, well worth investing some time into. It starts from simple definitions and concepts and builds up on them - very easy to follow even with little to no previous knowledge of the field.

Me too. Wrote a toy language partially referring to this back in '06. I still look back on that time fondly. It was one of those periods in my career where I was learning so many new concepts at once and it all felt like play. Much of my professional life really does feel like play still, but that was a sort of golden age. Ahh, memories.

I'm on a mobile device so can't view the book. Is familiarity with Haskell is one of the prerequisites to follow this? Thanks!

It wouldn't hurt, but given this paper predates Haskell by 3 years I think you're safe.

Would be more a history lesson of what eventually led to Haskell. IIRC Miranda might be a more apt comparison.
