Consider this corner case:

public class X {

    public static void main(String args[]) {
        Object o = "Hello";
        if (o __matches String x __matches boolean b1 __matches boolean b2 __matches true) {
            System.out.println(x);
        }
    }
}

I would expect x to be in scope inside the if {} - it is not:

/home/srikanth/tmp/X.java:6: error: cannot find symbol
            System.out.println(x);
                               ^
  symbol: variable x
  location: class X
