This is better than a standard for-loop from a maintenance perspective, 
but not from a usability perspective. It's just as much typing, or more. 
You still have to specify the container type. And if the container type 
is dependent, you'll need to insert a "typename" before iterator_of< T 
 >::type. It also requires you to have an understanding of iterators and 
half-open sequences, something that is not intuitive to people new to 
the STL way.
