23. Standard Library

HQL includes a comprehensive standard library with 107+ functions for functional programming. Approximately 96% of the stdlib is self-hosted (written in HQL itself).

Key Features

• Lazy-by-default sequence operations
• Clojure-inspired API (first, rest, cons, map, filter, reduce)
• Chunked sequences for performance
• Transducers for composable transformations
• Rich predicate and type-checking functions

Files

• spec.md - Complete function reference
