Leonid: Thank you for your careful explanation; very helpful. I was mystified by the error message, which seemed to complain that a symbol was not a symbol! But now, it makes perfect sense! Richard: In my actual situation (not the simple case I described), the function in question was already returning a list of values; which is why my misguided idea occurred to me. Thanks for your sugestion.
