A Reasonable Approximation

A Reasonable Approximation is a personal blog by a Haskell developer who writes about programming language theory, type systems, and practical compiler work. The site collects essays, dev logs, and talk notes, often exploring topics at the intersection of academic research and real-world Haskell engineering.

The core content includes detailed write-ups on prettyprinting approaches, GHC syntax implementation, and discussions of machine learning concepts like superposition and loss functions. Posts are technical and assume familiarity with functional programming, but they are written in an accessible, exploratory style rather than as formal papers.

This blog suits Haskell enthusiasts, compiler developers, and programmers interested in type-level programming and language design. Readers who enjoy deep dives into implementation details and thoughtful commentary on AI and software engineering will find plenty of material here.

To get the most out of the site, start with the tag index or the latest posts, and don’t miss the talk notes if you prefer a quicker overview. The writing is dense but rewarding, and the dev logs offer a rare look at real-world Haskell development. Overall, it’s a thoughtful resource for anyone curious about the craft of functional programming.
