Comment (by darij):
There is a difference between `vertices=[]` and `vertices=None`. In the
latter case, we should follow the cdd convention. In the former, we should
not; this kind of exception conflicts with regular usage. Currently the
constructor loses the difference between `[]` and `None` at one of its
first steps (the `_make_listlist` call); this is what I think needs to be
fixed.
