What Orwell's 1984 Can Teach Us about Programming
summary
Three Orwellian slogans map to concrete Scala techniques: war is peace becomes a war on effects using Option/Either/List plus Option/Either/List monads (flatMap/for‑comprehensions) to hide nulls, exceptions and multiplicity; freedom is slavery shows sealing ADTs and sealed ADTs and smart constructors so clients can’t build bad expressions and applicative map2 accumulates multiple error messages; ignorance is strength uses parametricity, Functor and a generic fuse/recursion‑scheme to combine translate+eval into a single one‑pass traversal that composes and compiles.
