And what if the object is from a class defined by a third-party module that I 
can't change?

I guess so, yes. My method would be something like what Jacob said, abusing
the memo dict to pass the copying mode. But I thought perhaps we can set a 
standard way for specifying different copy modes, because otherwise I'll do my 
memo hack and someone else will do his different memo hack and it won't be 
compatible.

I'll detail my hack later today when I'll be back home.
