Comment (by rws):
I don't know about the Python's ABC idea. Do we have a place for classes
that fit into that hierarchy?
This ticket grew on me because it forced me to learn a bit about abstract
algebra. After all this, I agree that this special `class Sequence` has no
place in `categories/` and that's what the ticket is about, too. However,
special subconstructs of the abtract idea of sequence would have a defined
place in the category tree, even though a superclass of all these might
not. But this is the topic of other possible tickets, and the `class
Sequence` of this ticket is not such a superclass.
