Sorry, I kind of screwed that up the first time. I meant to write this:

opacity:0.5;
apply-effect:opacity, background-image + background-color;

And you're right; I didn't originally account for multiple backgrounds. I
like the way you have it, and would say that background-image and
background-image(0) would be equivelent. So, without my messed up notation
on using this as a property, it would actually look like this:

 opacity:0.5;
apply-effect:opacity, background-image(1,2,4) + background-color;

'opacity' would be, but 'apply-effect' or 'visibility' would not be. It
would just continue to be the same throughout. So, if the effect
(opacity) only applied to the background, then you would be animating the
opacity of the background, and leaving the borders opacity, etc. alone.
