One of the primary reasons for this is primitives and instructions are wrapped in a huge switch statement in C, which is a pain to maintain by hand.
这样做的主要原因是基础实现和指令在C语言的声明中可以包装为一个大的switch表达式，如果使用手工的方式来完成无疑将会是非常痛苦的。
Extending the reach of the switch statement, not only to strings but also to other types, has been the subject of repeated enhancement requests over the years.

Ceylon also ensures (at compile time) that the switch statement contains an exhaustive list of instance tests or, at a minimum, an else clause to provide complete coverage.

Likewise, you might want to add assertions to else conditions in if blocks, where conditions are assumed, or to default cases of a switch statement, which should never be reached.
同样，您可能希望向if块中的else条件添加断言，这里已经设置了该条件，或者向switch语句中的缺省情况中添加断言，使缺省情况永远不可能到达。

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)。
