// Smart (ref-counting) pointer classes.  Uses "intrusive" approach:
// the types pointed to must have add_ref() and drop_ref() methods.
// Typically this is done by inheriting from a ref_counted class,
// although the nice thing about templates is that no particular
// ref-counted class is mandated.
