Hello Duncan,

I haven't gone in details of your very interesting proposal, so my
remarks are on surface.

- I think that it would be helpful to add serialization procedures.

- I don't understand why you wrote (srfi :287 graph) instead of just
(srfi :287). I'm not good at that so maybe you can explain me. However,
note that I prefer the latest notation of SRFI 261.

Regards
José
