bug#70209: 30.0.50; describe key + lambda too poetic

[No Wayman]

GNU Emacs 30.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version 
3.24.41, cairo version 1.18.0) of 2024-04-02  

emacs -Q --batch \
--eval '(global-set-key (kbd "c") (lambda () (interactive) t))' \
--eval '(describe-key "c")' \
--eval '(with-current-buffer "*Help*" (print 
 (buffer-substring-no-properties (point-min) (point-max))))'

Outputs the following poetry:

"c runs the command #<closure 0FE> (found in global-map), which is 
.

It is bound to c.

(anonymous)
"

"which is..."?
What is describe-key trying to tell us?
Is it respecting the function's wish to remain anonymous?
Is it commentary on the limits of descriptive language?
I can only respond with the output of M-x describe-feelings:

"It is bound to c, yet I see a bind:
Though closure mentioned, none I've yet to find."
