I really like the direction that this new syntax is taking wrt 
expressivity.  The curly braces
enable me to have nested optionals, built-ins everywhere they are 
needed, and a generally
useful disjunction (OR).  This makes the language much closer to SQL in 
Personally, I think its a mistake if DAWG specifies a query language 
that is significantly
less expressive than SQL.  On that issue, I'd vote for adding an ORDER 
BY (sort) clause.

On question:  If parentheses no longer enclose triple patterns, then 
what does the
syntax look like for prefixing a triple with "SOURCE var"?
