class Vars {
    record Point(int x, int y) {}
    enum Color {RED, GREEN, BLUE}
    record ColoredPoint (Point p, Color c) {}

    public static void main(String[] args) {
        var cp = new ColoredPoint(new Point(3,4), Color.RED);
        foo(cp);
    }

    public static void foo(Object o) {
        if (o instanceof ColoredPoint(var(var x, var y), var c)) {
            System.out.println(y);
        }
    }
}

The offending expression is:

   o instanceof ColoredPoint(var(var x, var y), var c)

where the first var is erroneously placed.
