Thread-topic: Mysterious type t_RFRAC and denominator function

WOW!! This extra argument for denominator/content/numerator is exactly what I need.
Up to now I had to do substitutions, relying on the priorities of variables "x" and "y".

Version 2.10 was the best so far from the summary in
http://pari.math.u-bordeaux.fr/archives/pari-announce-18/msg00001.html
(polrecip(1), derivnum(X=a,expr,{ind=1}), etc,etc), but 2.10.1 looks better still
