Two different issues here:

- The braces around the default graph in TriG make it fail in this role.
The syntax is always disjoint from Turtle, instead of being an
extension/subset thing.

- I'm also suggesting we allow (and prefer) "prefix" to "@prefix", and
require a "graph" keyword, to be closer to SPARQL.

I'm pretty sure these things will bug people for a good long time if we
don't change them now.   Only PREFIX/@prefix needs to be handled before
Turtle goes to LC.

Manu also makes the point that we have way too many syntaxes, but I
think that can be handled separately.

We could rename Turtle/TriG as the SPARQL Data Language or something,
and (someday) make it usable inside SPARQL.  :-)
