Print a tuple using get_head() and get_tail() in while-loop

[Alex Vinokur]

Suppose we have the following tuple
boost::tuple<int, std::string, bool, double> t (/* initialization */)

I would like to print that tuple using get_head() and get_tail() in
while-loop

while (/* What is a cindition */)
{
std::cout << t.get_head() << std::endl;
// What to do with t.get_tail()
}

You need to use a compile time recursion Its not as complicated as it
sounds, just some template specialisations to make recursion of a function..
See here for some example
