Comment (by darij):
Hmm, there actually *is* a noticeable amount of CombinatorialObjects which
redefine neither `__eq__` nor `__ne__` (tableaux, permutations, Dyck
words, partition tuples, ...), so we might want to check for speed
regressions. But they'll probably be insubstantial (for most combinatorial
operations, there should be no need to check for inequality).
Where can I learn how to use clonable lists?
About TestSuite: what am I doing wrong?
