/* A safe iterator is instantiated in the form
 * safe_iterator<Iterator,Container>: MSVC++ 6.0 has serious troubles with
 * the resulting symbols names, given that index names (which stand for
 * Container) are fairly long themselves. safe_ctr_proxy does not statically
 * depend on Container, and provides the necessary methods (begin and end) to
 * the safe mode framework via an abstract interface. With safe_ctr_proxy,
 * instead of deriving from safe_container<Container> the following base class
 * must be used:
 *
 *   safe_ctr_proxy_impl<Iterator,Container>
 *
 * where Iterator is the type of the *unsafe* iterator being wrapped.
 * The corresponding safe iterator instantiation is then
 * 
 *   safe_iterator<Iterator,safe_ctr_proxy<Iterator> >,
 *
 * which does not include the name of Container.
