 I agree. This is the reason I set this ticket to needs review even though
 it was failing tests all over the library. :)

 I tagged the 0.3.0 release already, but I can easily make a 0.3.1 if
 necessary.

 > But it would be really better to make these changes, if we plan to make
 them, before merging the ticket, so that people preparing books (I'm
 thinking of the french book which is in the process of being published)
 can expect their examples to pass for a quite long amount of time (or at
 least not to fail in the next version of Sage).

 Feel free to submit patches to pynac with necessary changes. I don't have
 time to work on this any more right now, but I can spare some minutes to
 make a new release with simple patches.

 That said, I'd really like this ticket to go in as soon as possible. It
 really is not fun to maintain the patch with the doctest fixes.
