To reproduce:
. emacs -Q
. Type into *scratch:
(add-hook 'mail-mode-hook
#'(lambda () (setq flyspell-generic-check-word-p
'mail-mode-flyspell-verify)))
. Evaluate the above expression with "C-x C-e"
. Type into *scratch*:
mail-mode-hook C-j
. The result:
((closure (t) nil (setq flyspell-generic-check-word-p
'mail-mode-flyspell-verify)))
Why are we present a simple lambda as a closure? why confuse users
with something tricky instead of showing the lambda-form the user
typed?
