In contrast dynamically typed languages bind the type to the actual value referenced by a variable, meaning that the type of a variable can change along with the value it references.

相反的，动态类型的语言则是根据变量所引用的值来绑定类型，这意味着变量的类型可以随着它引用的值改变而改变。

As an example, Listing 6 shows what happens when I change the type of the local variable used for the method start time in the interceptor code from long to int.

And remind you that inside of here, I'd better be changing the variable. All right, if that variable that's counting is not changing I'm going to be stuck in an infinite loop, so I ought to that, right, expect somewhere in there, a change of that variable. All right?

我最好改变了计数器的变量值，好，如果计数的变量没有变化的话，我就会被卡在一个无限循环里面,因此我应该【不可闻的声音】,对，在这里的某个地方，改变下计数器的变量，对不对？我要做的最后一件事情就是？
