Thanks for the reference, I'll take a look.  One one hand, a future-related
option is not going to be extensively documented in the reference manual.
On the other hand, thinking about it, it could probably be documented
at least in the Python `man' page, since the option exists as of now.
Probably not worth the fuss? :-)

Let me thank you, Tim, for this comprehensive and enlightening answer!
I'm carefully saving it for later meditation. :-)
