diagnostics: Add allow_unused_underscore config option#415
Merged
Conversation
Add a new configuration option `diagnostic.allow_unused_underscore` (default: `true`) that suppresses unused variable diagnostics for names starting with `_`. This follows the common convention in many programming languages where underscore-prefixed names indicate intentionally unused variables. When enabled, `lowering/unused-argument` and `lowering/unused-local` diagnostics are not reported for variables like `_x`, `__unused`, or just `_`.
