Comment:
Let me add that I discovered this bug while working on #11684, which is a
speed issue. Normally I don't care so much about speed, but in this case
things are really *far* too slow already; we should definitely not make
them any slower, especially since this is not necessary. Seemingly
innocent computations in Sage are often dominated by enormous chains of
type conversions rather than the actual computations they intend to be.
In conclusion: it may be a good idea to either use such a cached method or
avoid creating FiniteFields at all. ;).
