Another attempt to explain Haskell to the wilfully ignorant.
This post is an experiment I decided to attempt after conversations with Ben Lesh and some other folks. I will assume as little knowledge of Haskell as I possibly can here. Later we’ll talk about some tools we have in Haskell to make the pattern more conceptually compact.

Object.assign({ a: 42 }, undefined) –> { a: 42 }
