I don't know, is the author desperately trying to alienate Haskell to be cool? Dude, you're not cool because you don't understand something. :: is not always used for scoping, Sepples kiddie. It's like saying "wtf C has some kind of weird lists like x[i]. WTF? Oh wait, that's actual C syntax that happens to use the square brackets to index arrays and not denote lists. How quaint."
That man's mentally challenged. Furthermore, his behaviour enrages me.
