Now I understand what do you mean. I assume it can be done/

It should be similar to behavior of std::cin as it uses tie call so
apparently on the output side shoudn't be problem. (Also good point to
Regarding input it of course will be much trickier. More testing would
likely be needed and I see more potential problems.

I'll need to check it as well and if limitation exist report them
