Comment (by darij):
Nathann: done and done, although I'm not sure if I've done it the way
you've liked (please check).
Jori: I don't believe in this being of any help to users. Pronouns like
"this" become ambiguous very quickly when several objects are involved.
Here we have two lattices floating around and it's more or less clear
which one is meant, but I'd say that `self` makes it clearer. And when the
situation is more complicated, it is downright impossible to circumlocute
`self`. And the ugly truth is, users who don't know about Python are
screwed when they try to use our poset infrastructure anyway...
