It is much faster to say sum(1 for _ in graphs.nauty_geng(7)) than sum(1
for _ in graphs(7)), and after #19919 we have nauty as a standard package.
Will I break something if I change graphs(n) without any additional
parameter to use nauty? A user really needing the old code could then say
graphs(n, property=lambda x: True). I think that Sage documentation makes
no promise at all about the order in which graphs are generated.
