What I'd wish for is that I wouldn't have to be a human lint tool.
There are questions on CR where running the code through lint or a similar tool could give useful tips to the poster, especially for beginners who don't know about static analysis tools.
Posting an output from an existing tool wouldn't make for a good answer, but if it was tailored specifically for CR (justifying the review, including helpful links, using friendly language, etc.) maybe it could.
What do you think? Could a bot that posted automated review answers make sense? Or maybe a comment with a link to a report?
