Introduction里面只是泛泛的说了一下，
Notice that the assignment operator (`<-'), which consists of the two
characters `<' (“less than”) and `-' (“minus”) occurring strictly side-
by-side and it `points' to the object receiving the value of the expression.
In most contexts the `=' operator can be used as a alternative.
但是在什么情况下，`='不能作为`<-'的alternative呢？
如果所有的情况下都可以，那还要这个敲起来复杂而且有点weird的"<-"干什么呢?
毕竟大
