That's what I want, too.  The people saying we should implement COR
for columns seem to be, by and large, people who have never wished for
this feature and have no particular use case for either one.  I have
stated my use case in the past, but it has been dismissed as stupid or
contrived.  I can live with the possibility that I'm dumb, but, for
the record, I'm not making this up.
