I already abstract away the choice of boost::shared_ptr behind my own 
symbol, partly because someday I wanted to use perhaps an intrusive 
pointer instead and deriving from a common base class.  Because there 
are no template typedefs :( I had to do this by inheriting my class from 
boost::shared_ptr.

I wonder if it would be "distasteful" in any way to provide an operator 
==( int ) and a similar for !=?

bool GNE::SmartPtr<T>::operator == ( int rhs ) {
   assert( rhs == 0 );
   return ( *this );
}

(Yes I know there is another class called SmartPtr in existance -- I 
found that out later.  But that's why we have namespaces, no?)
