It might be reasonable to warn if a class has both a function marked 'override' and a function that overrides but is not marked 'override'.

That could be useful - because it means that the author of the class is at least thinking about override - but having a "coding style" warning of "I always intend to use override" would still be useful. Doug (not sure about other Clang owners) is pretty hesitant about implementing coding style warnings - anything with such a high false positive rate as to be off by default is assumed to be a non-starter in Clang (though perhaps things have changed in the years since I last tested the waters here). And now that we have something like clang-tidy, it's perhaps less of an issue... we'll see.

Making it part of clang-tidy would make a lot of sense then! Is there any plans to get clang-tidy running against the llvm/clang codebases regularly, or is it already happening?
