Comment (by davidloeffler):
I'm sorry, but "prime field" does ''not'' mean "field of finite prime
order". That's why there's a separate function {{{
is_PrimeFiniteField()}}}. A prime field is a field that is equal to its
own prime subfield, i.e. '''either''' a finite prime field or QQ.
I agree that the function should not return an !ImportError -- this is a
consequence of rearrangements in the finite fields code since the function
was written -- but it should be kept as originally designed, returning
True when the input field is equal to its own prime subfield.
