New policy for contributing to the Scala language - Announcements - Scala Contributors
Scala development goes AI-only, forbids human-written code! On February 24, 2026, we merged scala/scala3#25326, introducing a formal policy for the use of LLM-based tools in contributions to the Scala 3 compiler. That policy has already been effective. It reduced a whole class of low-effort AI-assisted pull requests, made contributors more explicit about how patches were produced, and gave reviewers a clearer basis for asking for local validation, tests, and prompt history when needed. However,...

Isn't Scala3 explicitly multistage?
Temper has a stages for:
- desugarings that make textual name assumptions,
- hygiene holds but new definitions can be introduced,
