#4 Missing closing parenthesis for some defmessage-handler examples (section 9.3.3.9)

[Andrew]

Here are code blocks from the basic_programming_guide.pdf page 125 ("107") section 9.3.3.9:

(defmessage-handler <class> put-<slot-name> primary (?value)
  (bind ?self:<slot-name> ?value)

(defmessage-handler <class> put-<slot-name> primary ($?value)
  (bind ?self:<slot-name> ?value)

At the very end there should be an additional ) to close the outer (.

P.S. Same with v6.40.
