Hi, I checked add-to-list fucntion in subr.el and I saw some fixme
comments. Is this actually a warning? If so, should this warning
return non zero status code when users specified `(setq
byte-compile-error-on-warn t)`?
I tried following command to compile:
----
$ emacs -Q -batch --eval '(setq byte-compile-error-on-warn t)' -f
batch-byte-compile ./foo.el
In foo:
foo.el:9:13:Error: `add-to-list' can't use lexical var `a'; use `push' or
`cl-pushnew'
$ echo $?
0
----
But, it returns 0. Is this desired behavior? or a bug?
