Quite frankly, I am not sure if catching that particular warning violation buys us much. As a return value from a function is never an lvalue, what triggers the warning may certainly be an indication of a sloppy coding, but otherwise I do not see it as diagnosing a potential error. "The programmer thought that the returned value will only be assigned to a const variable and will never be modified, but the language does not guarantee such a behaviour out of the caller"---does such an incorrect expectation lead to an error in the codepath that involves such a function?
