That's precisely what I'm talking about :-) Now imagine a query that's 
already complicated to start with, even without any reification...

If reification was directly supported, you'd expect something like this:

prefix dc: <http://purl.org/dc/elements/1.1/>
prefix sc: <http://purl.org/science/owl/sciencecommons/>
select  ?s ?p ?o ?by
from <http://purl.org/commons/hcls/proto>
where { ?s ?p ?o [ dc:creator ?by ] }
