I've noticed a few things missing from Norvig's new book "Paradigms of
AI Programming". Some text seems to be missing from the bottom of
page 198. Also, the end of page 202 mentions the updated function
"is" but doesn't give it in the text. Fortunately its given in the
ftp-able code listing:
(defun is (value &key (key #'identity) (test #'eql))
"Returns a predicate that tests for a given value."
#'(lambda (path) (funcall test value (funcall key path))))
Is there an errata list available? This book is really well done and
I'd like to get all the tidbits.
