The useless piece of shit doesn't even have syntax, let alone types, classes or typeclasses. When I read SICP, my eyes bleed because in order to explain the simplest things, the author has to implement every fucking elementary thing in a language that doesn't have any reasonable syntax; as a result, the point he was trying to explain gets lost in boilerplate and brackets.
Scheme is useless even for teaching purposes, let alone any production or research.
