I'm well and truly miffed—until this moment, I'd never come across this little jewel of a free ebook.🤦‍♂️

This book teaches practical #Haskell #programming (like monadic parsing) through an implementation of a large subset of R5RS #Scheme interpreter, all in just 138 pp. An experienced FP #programmer, even one who is unfamiliar with Haskell and Scheme (although I’ve not met such a person), can plough through this text, in one sitting.

It's brilliant!
