Mind you, that scoping mechanism would drive a truck through triple-store-based implementations, I suspect. Back to tree structures and Sexpressions, no doubt :-)

I think the arguments today have in fact shown that it is a lot easier and more useful
than people thought, so I think it could be done a lot sooner.

The issue of literals in subjects has more to do with some misunderstandings I think of
how complex and odd it is. I'd say let this conversation settle a bit. It really seems that
a lot of people have implemented it already.
