Now we just need to decide, what a recursive_wrapper is! Is it behave like a reference:
// # 1 union my_union { my_union& u_; int i_; };
Or is it behave like a pointer:
// # 2 union my_union { unique_ptr<my_union> u_; int i_; };
#1 is not what a recursive_wrapper is, because recursive_wrapper OWNS a value #2 is much closer to functionality of recursive_wrapper
[snip] So #2 would be like: int OR int* OR int** . . . int********.... Is that right?
