Sorry, please ignore the post of mine I'm replying to here.

I missed part of the thread, and Tim has already answered my question... That's news to Tim ;-)

You mentioned use of '...' / ELLIPSIS, IIRC, so I assumed that would work -- but it seems not, from your latest post (that I'm replying to here).

It's not possible to add a new doctest option in 2.5 that would allow a doctest to work under both 2.4 and 2.5: the test would blow up under 2.4, because 2.4's doctest wouldn't recognize the (new in 2.5) option, and would raise a ValueError of its own griping about the unknown option name.

Yes, that works, I see. Kind of annoying of course, but can't be helped.

Hmm, will 2.5's doctest work under Python 2.4? I guess that's not guaranteed, since I don't see any comment in doctest.py implying it needs to be compatible with old Pythons.

Oddly enough, ELLIPSIS doesn't actually work for this purpose: [...]
