Indeed, it's a mere warning about a failure to apply an optimization.

But I do think it's a bug (I think we discussed this a few months ago,
probably in some other bug report): we should inhibit compiler macros
(and silence any other macro-expansion warnings)
during this kind of completion since it's normal to have
incomplete/invalid code at that point.

The warning in valid and meaningful in other situations (e.g. if you
were to compile code that contains just `(add-to-list f)`), but here
it brings no value.
