Pattern matching on Array types, working for reals.
def f[T](a: Array[T]) = a match {
case x: Array[Int] => x(0)
case x: Array[Double] => 2
// etc.
}
I'd also like to thank "instantiateTypeVar" for displacing the
mechanical spiders and giant squid beings which used to fill my
nightmares. Now that I know true horror, I welcome the squid.
Closes #2755, review by odersky.

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.
