Thanks very much for this response. Indeed, it compiles if I move my 
overloads into the same namespace as Gr. I'm not sure why I didn't think 
of trying that! Many thanks for the fix.

I still find it a bit surprising... I guess I need to re-read the ADL 
rules. :-) I'm pretty sure I've seen some examples in the online 
documentation which don't follow this pattern (e.g. the LEDA graph 
adaptation tutorial) but no doubt there is some other intricacy of 
name lookup that makes them work....

Thanks again!
