Comment (by tscrim):
Ah sorry, I upgraded to `beta2` but uploaded from the old one.
Since this is a niche thing IMO (wrt the rest of Sage), it's worthwhile it
lazily import it to help keep startup time down. As far as the `ZZ`
import, it just makes things easier for me to remember; I don't think
there's an explicit difference other than having extra unneeded (in a
loose sense of the word) variables running around.
