So, I've taken the challenge more seriously:<br>

I should also add that it's possible to turn this proposal into
support for hypergraphs.<br>
<br>
All that would need to be done is to have "to" and "from" be
arbitrary objects instead of keywords, so that edges can connect to
as many vertices as desired, rather than just having directionality.
And then something like the "fromto" keyword could just be a tuple
of these.<br>
<br>
I don't think this would make any serious difference to the
implementation. However, hypergraphs are known to cause migraines:
I've tried to keep the proposal as painless as possible at this
point!<br>

Another thought is that "to" and "from", rather than being keywords,
can be special values, like True and False. So, you could then use
To and From for relationships, and ToFrom can equate to a tuple:
(To, From). Voila: hypergraphs with Tylenol.<br>
