I have written a helper class that holds a reference to a
boost::adjacency_list object. When writing the assignment operator for that
class, I (apparently naively) called
    this.m_g = other.m_g;

In this case, my helper class should hold a pointer rather than a reference.
That way I can copy an address rather than copying an object, which is what
I really want anyway.

I guess this is a rather long-winded way of saying: I don't know of a
situation where one would use g = g.

Thanks for your reply,
David
