Forget the previous message, which is about `dolist'. I mixed my examples.
The original trouble with `loop' is that, in a loop like this one,
with destructuring
(defsubst my--bs-file-width ()
(- (window-width)
(loop for (name width . rest) in bs-attributes-list
if (numberp width) sum width)
(bs--get-name-length)
1))
`name' is just a placeholder (as it is rest). I'm interested just in
`width'. And there's no way to write that loop as is without warnings.
Interestingly, `rest' does not produce a warning.
I suppose I can rework the loop to avoid the restructuring, but it
seems like a loss of clarity.
