subject Wrong unboxing of arrays
code 
object Main {
  def f[T1, T2](x: T1 => T2): Unit = ();

  def main(args: Array[String]): Unit = {
    f(args)
  }
}
what happened 
A ClassCastException at run-time:

scala $ ~/projects/scala-stable/bin/scala -cp /tmp/ms/classes Main
Exception in thread "main" java.lang.ClassCastException
	at Main$.main(bug_arrays_2.scala)
	at Main.main(bug_arrays_2.scala)
what expected A normal run. It seems that when passing the array to function f, it is passed unboxed, which is incorrect.
