You could simply return a pointer to a standard C++ object (if you don't need to access functions), any other type of function lookup table, or whatever you wanted.

The reason C and C++ never adopted nested functions is because in order to make capture work, you need additional information, with the result that a pointer to function becomes more complex.
C和c++的原因从未采用嵌套函数是因为为了使捕获的工作，你需要额外的信息，其结果是一个指针函数变得更加复杂。
