Comment:
Nathann,
It was said in some web page that a code like `[c for c in
self.cover_relations_iterator()]` is slower than
`list(self.cover_relations_iterator())`. Is it true? If so, please mark
this as needs_work and I'll do that also. (And `[z for z in
range(self.order())[x:y+1]` seems odd too.)
If not, this is free to review.
