I very much agree, which is why I posted my view on the rules we can use
for comparing them.

The code I posted returns tuples which should be directly comparable. I
believe they define a good ordering, but it would also take a bit of
review to see what happens when elements are inserted/removed (e.g. the
a2 at the end of 1.5.2a2)
