We experimented with different uses for pattern matching, a powerful improvement on the familiar case-switch statement.

Another useful rule of thumb: it's typically not cost effective to inline functions with loops or switch statements (unless, in the common case, the loop or switch statement is never executed).

其他有用的经验法则：一个函数如果有判断或循环语句通常是没效率的。(除非在通常的情况下循环语句或判断语句不会执行)。
