Data-directed programming in Haskell (SICP 2.4.3)

The author explores data-directed programming in Haskell, as introduced in SICP section 2.4.3, focusing on complex numbers that can be represented in both rectangular and polar forms with operations to query real, imaginary, magnitude, and angle values.

Background

SICP (Structure and Interpretation of Computer Programs, often called "The Wizard Book") is a legendary computer science textbook from MIT that uses Scheme (a Lisp dialect) to teach fundamental programming concepts. This article translates one of its ideas — data-directed programming — into Haskell, a modern functional programming language.

Max Weinbach says he had early access to OpenAI's new model GPT-5.6 Sol, calling it his favorite model by far. He highlights that it never gives up and will keep reasoning until it's done. OpenAI announced that GPT-5.6 Sol, along with Terra and Luna, will launch publicly on Thursday, with preview access expanding globally now.
