Ralf Thomas Walter Hinze · Journal of Functional Programming · 2003
When I was a student, Simula was one of the languages taught in introductory programming language courses and I vividly remember a sticker one of our instructors had attached to the door of his office, saying “Simula does it with class”. I guess the same holds for Haskell except that Haskell replaces classes by type classes.
