Comment (by rbeezer):
I'd say this is the '''right''' thing to return, it is extremely standard
to quote all four at once. At a minimum it is a big improvement. Two
initial comments.
1. Patch has some changes to `coloring.py` that look totally unrelated.
Should they be somewhere else?
1. What if somebody currently does
{{{
g.is_strongly_regular(return_parameters = True)[1]
}}}
because all they want is `lambda`. Now they will get `k` and be none the
wiser. How about deprecating the current keyword and make up a new
(similar) one? Or maybe there is a better fix that I am not thinking of
right now. (There is an easy decorator for deprecating a keyword, iirc.)
Just `parameters` would be cleaner, imho.
