Well, what I have to do is to iterate through each and every element of the
container and calculate validity of the element. If current element fails the
test I don't have to continue further. I don't think that std::find_if would
work in this case.
My question is more to how the control structure of "lambda" library works in
respect to "return" or "brake" in the cycle.
