	fmt.Println(p1, p2, p3) // &{0 0} &{0 0} &{2 3}

	x := new(int)
	fmt.Println(x, *x) // 0xc00001e158 0

	p := new(chan int)           // p has type: *chan int
	c := make(chan int)          // c has type: chan int
	fmt.Printf("%T, %T\n", p, c) // *chan int, chan int

new(int)        -->  NEW(*int)
new(Point)      -->  NEW(*Point)
new(chan int)   -->  NEW(*chan int)
make([]int, 10) -->  NEW([]int, 10)
// 非法操作
make(Point)  // Illegal
make(int)    // Illegal
