Serql has the capability now, and apparently Jena has had api solution
involving prebinding (not sure how long this has been around).

When we first started this conversation, I was in agreement with you -
that if we found a non-conflicting solution that it would be enough to
postpone it until SPARQL 2.  However, during the course of the
discussion I've seen enough incompatible ideas already in use that I
think a consensus on the issue would be a very Good Thing.
