    10  // unusedresult: check for unused results of calls to some functions
    11  //
    12  // Some functions like fmt.Errorf return a result and have no side
    13  // effects, so it is always a mistake to discard the result. Other
    14  // functions may return an error that must not be ignored, or a cleanup
    15  // operation that must be called. This analyzer reports calls to
    16  // functions like these when the result of the call is ignored.
    17  //
    18  // The set of functions may be controlled using flags.
