[Link] Purely Functional Data Structures in Clojure: Leftist Heap

Last year I started reading a book called Purely Functional Data Structures. It’s a fascinating book and if you’ve ever wondered how Clojure’s persistent data structures work, it’s mandatory reading.

However, all code samples in the book are written in ML - with Haskell versions in the end of the book. This means I got stuck in Chapter 3, where the ML snippets start.

I had no clue about Haskell’s - much less ML’s! - syntax and I was finding it very difficult to follow along. What I did notice is that their syntaxes are not so different from each other.

So I put the book down and read Lear You a Haskell For Great Good! with the hopes that learning more about haskell’s syntax - in particular, learning how to read its type signatures - would help me get going with Puretly Functional Data Structures.
