How does "typename" work here?  I'm not familiar with recent C++
developments...

Hmm.  I don't really know how that works, but I think I prefer this:

    typedef std::set intset_t;
    intset_t cont;

    cont.insert(5);
    cont.insert(7);

    intset_t::iterator it = cont.begin();

    while (it != cont.end())
    {
        // do something with *it
        ++it;
    }

Having said that, my personal preference is a bit academic - as these days
I spend most of my programming time writing code in Python :-)

  cont = set()
  cont.add(5)
  cont.add(7)

  for it in cont:
    print it
