Mentioned on the #emacs channel (libera).
As per https://www.gnu.org/software/emacs/manual/html_mono/transient.html#Suffix-Specifications
– it is mentioned that "COMMAND can also be a lambda expression."
However, evaluating the form (even on an Emacs instance started with "emacs -Q")
(transient-define-prefix my-test-transient () ["Heading" ("a"
"choice a" (lambda () (interactive)))])
Results in the following warning being printed on the *Messages* buffer:
Warning: (lambda nil \...) quoted with ' rather than with #'
Attempting to hashquote the lambda as in:
(transient-define-prefix my-test-transient () ["Heading" ("a"
"choice a" (lambda () (interactive)))])
... as suggested by some on #emacs results in an error when evaluating.
At this point, I am not sure if this is an error in documentation of
transient.el, or an error in the macro definition of the
`transient-define-prefix' macro itself, or if the warning is
superfluous and whether it should be ignored. As I'm unsure whether
this is a bug or not, I'm erring on the side of safety and reporting
it to bring it to attention.
