)

func main() {
    var p *point2d.Point = new(point2d.Point)
    fmt.Println(p) // Automatically calls p.String()
    p.Set(3, 2) // Set's the Point's position to (3, 2)
    if p.Equal(3, 2) {
       fmt.Println("p is equal (3, 2)")
    } else {
       fmt.Println("p is not equal (3, 2), p is", p.String())
    }
    var p2 *point2d.Point = point2d.AsPoint(3, 9)
    var dist int = p.DistanceTo(&p2)
    fmt.Printf("p is %d away from p2\n", dist)
