Tighter pattern matching hits the street.
is final and does not conform to the pattern, it will no longer compile.
See all the exciting things you can no longer do:
"bob".reverse match { case Seq('b', 'o', 'b') => true } // denied!
"bob".toArray match { case Seq('b', 'o', 'b') => true } // rejected!
final class Dunk
def f3(x: Dunk) = x match { case Seq('b', 'o', 'b') => true } // uh-uh!
And so forth. Review by odersky.
