[plt-scheme] Re: plt-scheme Digest, Vol 3, Issue 12

I'm not sure if this is off-topic, but I've been
trying to come up with a good representation for
molecules like the benzene molecule.  Ideally, the
representation in scheme should include the fact that
any given carbon atom has both a single and double
bond as well as a Hydrogen attached.  The structure
should include the ring nature of benzene (not worried
about bond angles yet but they probably should be
considered.

I've thought of using the shared environment.

Does anyone have any ideas?
