      Description

      The following query does not parse.

           prefix : <http://example.com/>
           SELECT ?a {
              ?d ?e <<?a ?b ?c>> . 
           }
      

      The problem is demonstrated by TestReificationDoneRightParser.test_triple_ref_pattern_all_vars() in the test_rdr branch.

      The root cause is likely the openrdf 2.7 migration (BLZG-805). I suspect that we lost part of the RDR grammar when that migration was implemented.
