1) would it be easy and desirable to make the patchbots run tests in
random order?
Easy: yes
Desirable: no, it would create a lot of doctest failures
2) concerning https://trac.sagemath.org/ticket/26586, is it desirable to
define comparison for `CartesianProduct`?
Absolutely. If you do that, you should open a new ticket.
3) at first I thought that it is good practise to sort output whose
order is essentially random
I agree.
5) would it be a good idea to have `__repr__` use a "sorted output" for
objects that are sets from a mathematical perspective?
I would say yes, but this wouldn't really solve the problem since the
function returns a list, which is not sorted.
It's important to note that such sorting should be restricted to
__repr__. For example, the method Poset.upper_covers() should not sort,
for 2 reasons:
(a) not all objects can be sorted, this is in particular a problem in
Python 3 (see graphs for a bad example)
(b) performance: most of the time, you don't care about ordering
