which results in "unpack non-sequence" when we *don't* return
a tuple...  hence I previously decided to always return a
tuple... however, the caller *knows* when it'll receive a
tuple (when get_col_idx is not None, that is) so we *can* know
beforehand what sort of result we get, hence I implemented
Ian's suggestion
