def find(explore: List[(seen: Set[Int], x: Int, y: Int)]): Any =
  explore match
    case Nil => ???
    case (seen = s, x = x, y = y) :: rest => ???

Output

-- [E029] Pattern Match Exhaustivity Warning: ----------------------------------
2 |  explore match
  |  ^^^^^^^
  |  match may not be exhaustive.
  |
  |  It would fail on pattern case: List(_, _*)
  |
  | longer explanation available when compiling with `-explain`

Expectation

the named tuple pattern will always match, so no warning
