// 接管普通函数指针void(_Undefined_class::*_M_member_pointer)();// 接管类成员函数指针};class_Undefined_class;对_Function_base的操作均是通过其内部模板类_Base_manager进行的，_Base_manager提供了很多接口，源码如下所示，大家看注释可以有一个宏观的理解，具体细节后面
在非捕获lambda的情况下,使用函数指针比使用更快std::function.这是因为它std::function是一种更为通用的野兽,并使用类型擦除来存储传递给它的函数对象.它通过类型擦除实现了这一点,这意味着你最终会调用operator()
