About
Simon Peyton Jones, co‑creator of Haskell, links functional programming to immutable values rather than mutable state and data. Haskell's GHC front end parses source, performs type checks, and translates code into the small Core language with dozens of constructors. Strong static type systems reduce vulnerabilities, enable systematic refactoring, and guide safe parallelism in modern software.
Key points
- Functional programming origins trace to lambda calculus by Alonzo Church and equivalent Turing machine model
- Haskell isolates side effects, exposing unsafePerformIO as the only way to execute impure actions
- Research explored hardware like MIT Dataflow machines and SKI combinator machines, but compiler techniques proved more effective
