Data-directed programming in Haskell (SICP 2.4.3)

The blog post discusses data-directed programming in Haskell as presented in the influential book 'Structure and Interpretation of Computer Programs' (SICP). It contrasts the representation of complex numbers in rectangular and polar forms, and aims to provide insights on how to effectively query these representations. The author takes a personalized approach by selectively engaging with the book's content that interests him.
