I just wanted to point out that (doc 'need) for version 15.11.0 seems to miss something. It defines the possible arguments of need as:
(need 'cnt ['lst ['any]]) But it doesn't say what the function does with 'any, or how it affects the result. I also wanted to ask if this kind of topic was appropriate for the mailing list. It seems so small that I wouldn't want to bother everyone just to point it out.
