Overloading operator << - C++

Question

Background

I have a container class which uses vector internally. I have provided a method AddChar(std::string) to this wrap

Answer 1

This is going to make things rather confusing, I would use the same syntax as std::cin into a variable:

std::cin >> someint;

"First" >> container;

This way it is at least an insertion operator. To me when anything has a << overloaded operator I expect it to be outputting something. Just like std::cout.
