With patch applied, thy *scratch* prepared to itch which I bemoan,
*Help* link replied, its ink ensnared, with "lambda, type 
 Unknown."[1]
Apostrophized: "Be tossed, repaired, my user-error thrown!"
With paren pride, I then declared a test which I have shown.[2]
Test now revised as thou compared. Composure hath no throne
when teary-eyed, in fear I blared, "My closure! Type Unknown?"


[1]:
emacs -Q --batch \
--eval '(global-set-key (kbd "c") `(lambda () (interactive) t)))' 
  \
--eval '(describe-key "c")' \
--eval '(with-current-buffer "*Help*"
           (forward-button 2)
           (push-button)
           (print (buffer-substring-no-properties (point-min) 
           (point-max))))'

Unknown type lambda
