"Pair" can be synonymous with "cons", which is not what you mean here.
"Properties"?

This technically works, but `setq' is a strange thing to see in an
`and'. But the problem isn't the `setq'; it's that crazy `and'. I'd
replace the `and' with `when', keep the `setq' and `plist-put' in the
body, and squint a lot less at this code.
