3 Commits • 1 Features
Oct 1, 2025Month: 2025-10 — This month focused on a foundational terminology refactor that improves clarity and consistency across the hazel project. Key features delivered: Terminology Standardization renaming 'Product' to 'Tuple' and 'nonlabel' to 'unlabeled' across the type system, string representations, and user-facing messages. The work reduces ambiguity and sets the stage for easier localization and onboarding. Major bugs fixed: none reported this month; the changes were structural and naming improvements. Overall impact: clearer API/UI terminology, reduced support friction, and cleaner code paths for future development. Technologies/skills demonstrated: OCaml/ReasonML codebase refactoring, type-system terminology alignment, and precise commit tracing (Typ.re updates).
