Slava's Monoid Zoo is a technical exploration of how finitely-presented monoids and the Knuth-Bendix completion algorithm underpin Swift's generic type system. The article walks through the word problem and shows how generic requirements in function/type declarations are represented as relations in monoids.

Swift's generic type constraints are mathematically grounded in monoid theory and the Knuth-Bendix completion algorithm, which solve the word problem for finitely-presented monoids.
