Even if it was useful in some cases, it would be extremely
wasteful in general.
I believe you, but could you explain why, so I can learn? I don't know much
about how C interfaces with Lisp. Is it because a new OBJECT would in fact
need to be created? I was thinking that the operation could just return (the
equivalent of) a pointer to the original OBJECT. IOW, where is the waste?
I guess, in the case of a buffer, a new string would need to be created. Is
that what you meant, or is there also a problem when the OBJECT (string)
argument is explicitly supplied?
