Well, yes,  that makes it easier to read and write and we can have our key words
back.   But I still like my solution better (course i would).   Fluff key words just
give us syntactic brambles to parse around and encourage people to extend  the
language is a ways that diverges from labeled directed graphs.  That later problem
being more important than the typographic one.

Also, while we're at it, why not eliminate prefixes entirely.  Here's how ... though
I bet somebody though of it before i did.  We define the default namespace somewhere
[talkingIn="http://swag.semanticweb.org/termsplayground"] ... then require that to
be a coherent dictionary inheriting all necessary namespaces and that it contain no
conflicting antonyms (did i get the right word here?).
