One example I can think of that could be useful is if UA X supports both
properties A and B, but UA Y only supports property B. One might want to
have UAs that support property A to use it and those that don't to use
property B, but not for those that support both to use both. In that case
selector { propA: value, else(propB: value); } could be useful. I can't
seem to track it down now but I remember there was talk about allowing
extensions to css syntax with properties prefixed with a -. Having the
ability to fallback would be useful in such cases.

After all, what is your hosts' purpose in having a party?  Surely not for
you to enjoy yourself; if that were their sole purpose, they'd have simply
sent champagne and women over to your place by taxi.
