An educational article clarifying the confusion between module systems (as in OCaml) and typeclasses (as in Haskell/Rust). Typeclasses provide ad-hoc polymorphism for reuse across types, while module systems enable modular abstraction for organizing large programs.
Background
Typeclasses and modules are foundational abstractions in functional programming languages, often conflated by developers learning multiple languages. This article is part of an ongoing educational discussion on language design patterns.
