当完成该函数之后，使用返回指针回到原来的位置并继续程序。

After the function has been completed, the return pointer is used to go back to the original location and the program can continue.

从调用函数处返回指针后，将在指定的返回指令指针处恢复执行。

Upon returning from the called function, execution will resume at the saved return-instruction pointer as specified.

答案是它们不必知道；在返回指针之前，我们会将其移动到这个结构之后，把它隐藏起来。

The answer is that they don't have to know about it; we will hide it by moving the pointer past this struct before we return it.

It says, if I want to print out something I built in Cartesian form up here, says, again, I'm going to pass it in a pointer to the instance, that self thing, and then I'm going to return a string that I combine together with an open self and close paren, a comma in the middle, and getting the x-value and the y-value and converting them into strings before I put the whole thing together.

这不仅仅是个列表,它是怎么来做的？,流程是：如果我想要返回,一些已经在笛卡尔模式下建好的值，好，再说一遍，我首先要传入一个,指向实例的指针,也就是，然后我会返回一个,由开括号，闭括号,中间的一个逗号,以及提前转换为字符串格式的。
