Hi there,

I want to query if there's any interest in such a utility:

    span(iterator, size) : iterator_range

which simply returns iterator_range(it, it + size) for RandomAccessIterator;
for others modeling ForwardIterator, a special iterator adaptor, say,
counted_iterator is used, so we don't have to advance it just for getting
the end iterator.

Thoughts?
