[boost] smart_iterator

Cant remember hearing about anything in this vein. Maybe someone
who knows smart_ptr better, has a funky way of applying it?

Below is a hack of the idea. Actually coded something similar and
then realised it was a repeat of smart_ptr. But couldnt neatly apply
it.

set<string>    identifier;
string            token;
{
    smart_iterator<set<string> > f;

    f = identifier.find( token );
    if(f != identifier.end())
    {
        // Do stuff    
    }
}    // Automatic set<>.erase() in dtor of "f"
