This time, a string concatenation has occurred within the same method, and the input parameter is now bound to a String type argument at function execution time.

这次，相同方法内发生了字符串串联，并且现在输入参数在函数运行时受到 String 类自变量的限制。

The AddOne method is not a very practical example because you would normally just receive a regular integer as a parameter and write the method as a function that returns a modified integer.

方法addone并不是一个很实际的示例，因为通常只需接收常规整数作为参数，并且作为能返回修改的整数的函数编写此方法。

It is this that allows us to do the trick of printing out the parameter "p" and then passing it to the "rest" function to continue the computation, seen here in the definition of the "Bind" method.

这样话，就可以让我们能取巧打印出参数“p”并接着把它传递给“rest”函数继续进行计算。
