If you send a variable x to a method y and the value of x is changed inside y, you cannot obtain the changed value of x from outside the method—unless the method explicitly returns that value. Ruby语言严格遵循了这个原理.

but will just return a NULL result automatically. In a non-strict function, if the actual value of an argument is NULL, the correspondingargNvariable will be set to aNULLR object. For example, suppose that we wantedr_maxwith one null and one non-null argument to return the non-null arg...
