That wouldn't be the computed value, but rather the used value, which
is extra-hard.  It basically can't be done in a declarative system
like CSS.

It's not blocked.  Property references on the element (thematically
similar to current var() function) are pretty much out automatically,
so no worries there.  Property references to the element's parent
*might* be possible, and there's nothing messing with that right now.
