Type Safe Generic Data Structures in C
Daniel Hooper shows a technique for type-safe generic data structures in plain C that uses unions to attach type information to a generic container, building up from a basic linked list and comparing it with macro and void-pointer approaches so the compiler catches type errors at call sites.

TypeScript and Haskell: Unions & Singletons
Gabriel Garcia explores how TypeScript's combination of union types and literal (singleton) types gives APIs precision, then tries to reproduce the same pattern in Haskell with type families, unboxed sums and singleton naturals, showing where the encodings get awkward and why they fail to behave like a set of types.
