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