昆明是一个美丽的地方,有一天我会去那里。
因为那正是我会去的第一个地方…似乎我们终于有共同点了。
'Cause that's exactly the first place I'm gonna go. Turns out maybe we got something in common after all.
So I actually want to have type checking as much as I can early on.
因此我会在尽可能早的地方去,做一个类型检查。
I'm using it as an abstraction, saying I'm going to have square root from somewhere, maybe I'll build it myself, maybe somebody gives it to me a s part of a library, so I'm burying the details inside of it.
我把这个方法作为一个抽象来引用,意味着我将会从另外一个,地方去求一个数的平方根,可能我会自己写这个方法,也可能我会从别人写的lib中去引用,因此我将实现的细节放到了其他地方。
