AOP allows us to execute an arbitrary function when a specified method is called.
AOP允许我们在指定的方法被调用时执行任意的函数。
Methods also support accessing (but not setting) the arbitrary function attributes on the underlying function object.
方法也支持获取(但不(能)设置)函数的任意属性?
This is normal, and the arbitrary function all can approach with dividing section multinomials because can know from infinitesimal calculus.
这是正常的,因为从微积分可以知道,任一函数都可以用分段多项式来逼近。
