I folded the reviewer's patch in the original patch. All test pass and the new code is semantically equivalent, but way faster. Positive review! Thanks!

There is a little problems with duplicated references in meet_matrix
and join_matrix
.

Nice catch ! There's no warning anymore when I generate the doc, so I guess the new patch can go too :-)

Helloooooooooooo !!!
I added two modifications (which did not appear to make much of a difference) but also make the code slightly easier to read. There already was a reference, I added another, no one is hurt
:-)
If you are ok with this second set of modifications you can set the ticket to "positive_review".
