No, it is a good IDEA. Maybe not such a good proposal. The details  
might need a little work, though its hard to do it right because that  
would break SPARQL. Basically, if we had caught plain literals before  
SPAQL was set in stone, things would be a lot better, but they aren't,  
so some messiness is inevitable.

BUt it can do some things that current RDF cannot do, such as have  
typed literals with language tags, that are urgently needed out in the  
real world.

No need to escape the @ because it is used in a fixed position. Which  
is also ugly, but hey ho.
