One of the advantages of this is, that I don't have to worry about explicitly updating my variable. That happens for me automatically.
这样继续下去,这样做的一个优点是,我不用为更新变量来发愁了,程序会自动的为我进行这个操作,这一点很好。
If somewhere later on in the code it shifts to string, I might not be manipulating that and getting actual values out, but not what I wanted, and it's going to be really hard for me to chase it back.
然后后面的一些代码,把变量类型变为了字符串,我可能不会通过实际操作,去取得实际的变量的类型,但是这并不是我想要的类型,而且对我来说把类型,变回去也很困难。
