hi,
Nikodemus, i've seen your comment regarding r-f-p. i have more or less copied r-f-p from arnesi and unfortunately didn't give it enough thoughts and therefore the current argument order just a heritage.
the (r-f-p plist &rest keys) signature looks much better and performance can be have through inlining the calls, so i suggest to simply changing r-f-p to that signature, and recording the change with a big fat warning.
