Comment(by wdj):

 I have not applied or tested this patch but upon reading the code a few
 lines struck me as odd. Can you please explain how, if F is a finite
 field, F.order() -> F.cardinality() is correct? Has the order method for
 finite fields been rewritten? Did I miss the discussion on sage-delev that
 order should be deprecated and replaced by cardinality?
