Compiler version

3.0.0-RC1

Minimized code

List(1, 2, 3) match
    case x :: y :: Nil => ()
    case Nil => ()

Output

match may not be exhaustive.

It would fail on pattern case: List(_, _, _, _: _*), List(_)

Expectation

Warning should be the following?

match may not be exhaustive.

It would fail on pattern case: List(_, _, _, _ *), List(_)
