// Makes sure that a helpful message is shown when someone mistypes
// an inclusive range as `..==` rather than `..=`. This is an
// easy mistake, because of the resemblance to`==`.
// See #86395 for a bit of background.

    if let 1..==3 = 1 {} //~ERROR unexpected `=` after inclusive range
                      //~|HELP use `..=` instead
                      //~|NOTE inclusive ranges end with a single equals sign
