Error Models for Systems Programming Languages: An Epic Treatise

This 15,000+ word blog post delves deep into error models for systems programming languages. The author approaches error representation, propagation, and handling from multiple perspectives: product, type system, and language design. A hypothetical language, 'Everr', and its error model are proposed, aiming for a balance between graceful degradation, performance optimization, and interoperability between libraries. The post compares error models across various programming languages and explores programmers' understanding and handling of errors.
