> Thanks Jason! I am uploading a patch to convert the tuples of
coordinates to strings before comparing and I hope this solves the issue.
I'm not sure we should ignore the order in coordinate tuples. For
instance, T(T*Q) has natural bundle coordinates (q, p, q', p') whereas
T*(TQ) naturally has coordinates (q, q', p, p'). The two bundles are
isomorphic by switching the relevant coordinates, but it would be good to
keep the distinction.

I meant, do you want to force a total order on the set of coordinates? In
other words, what does (q,q',p,p')<(q,p,q',p') mean? Or do you just want
to have equality testing, i.e., you can tell that (q,q',p,p') !=
(q,p,q',p')?
Regardless, I think resolving that design issue should be a separate
ticket.
