Then again, later on in the very same book there's a chapter entitled "Fun with Phantom Types", which made precisely no sense at all...
(I find this a lot with Haskell. There is stuff that is clearly written, fairly easily comprehensible, and extremely interesting. And then there's stuff that no matter how many times you read it, it just makes no sense at all. I'm not sure exactly why that is.)
Agreed, that does seem to happen a lot. I was utterly baffled by the chapter on functors in HSE. It wasn't until I spent a rainy weekend on my own in Aberdeen (harsh, I know) that I read the chapter enough times to figure what it actually meant. Of course at that point I thought it was fabulous and wanted to tell someone. But I was still alone in the greyest city on Earth... D.
