The code sample at the top of the page is much debated, and despite the evident problems with it, alternatives proposed have seemed worse for various reasons. There’s an open ticket that discusses this and other issues with that code sample code here: https://github.com/haskell-infra/hl/issues/46

Anybody that wants to make a stab at redesigning the top so that it A) has a code sample demonstrating many language features, B) can’t be poked at for not being the “real” this or that, and C) can be typed or translated directly into the REPL, please have at!
