Data-directed programming in Haskell (SICP2.4.3)

The article explores implementing data-directed programming in Haskell as an alternative to tagged data dispatch, following Section 2.4.3 of SICP. It addresses the maintainability issues of adding new representations in traditional tagged approaches by decoupling operations from specific data formats.

Background

Structure and Interpretation of Computer Programs (SICP) is a foundational computer science textbook that uses Scheme to teach programming concepts. Data-directed programming is a technique used to manage multiple data representations without modifying existing generic operations.
