I don't see how such a warning would be particularly useful in practice. Wouldn't one of these two things have to be true? 1. It would only warn you when you used the typo-prone pattern but didn't actually make any typos in it 2. The warning would trigger in code where the author intentionally breaks the pattern for some cases
