Ok, without checking, what do you think happens? (List(0): Seq[Int]) match { case _: List[Int] => 1 case _ => 2 }

Even more fun, what do you think happens: (Seq(0): Seq[Int]) match { case _: List[Int] => 1 case _ => 2 }

It does, but your answer makes me feel I've missed something obvious - it seemed less intuitive to me that the runtime type of Seq(1) was List than that of List(1)...

Yes, you would need to know the specific implementation of `Seq#apply`... which is somewhat arbitrarily a `List`.
