compile false alarm warning

fn op_equal[T : Eq](self : Cell[T], other : Cell[T]) -> Bool {
  loop self, other {
    Nil, Nil => true
    Cons({ content: x, next: xs }), Cons({ content: y, next: ys }) =>
       x == y &&
        continue xs, ys
      
    _, _ => false
  }
}

Warning 018: There is no [continue] in this loop expression, so [loop] is useless here.

this seems works as intended but the error shadows the warning
