Here is an easy use case - one wants to know how many elements are in the
input sequence _before_ the actual processing happens, even if at the cost
of additional iteration through the sequence:
template< typename Iterator >
void do_input(Iterator first, Iterator last)
std::size_t size = std::distance(first, last);
// using size/fist/last...

I thought it's being submitted as a part of Spirit anyway ;). IMO it's
definitely should be factored out into a standalone mini-library.
