- on stderr (finch ir stays the IR), as yellow warnings in editors (@W in the index), once per place - str, arrays and maps inside a struct don't count: passing it copies only their handles - none in the compiler, the examples or the tests other than the new one - docs: the warning instead of "not planned"; what was and wasn't checked for Android Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_016GzNP6r8dg6WDxUVZy8wjL
