Note: I did not post the message to the list.  I sent a private email to 
Rich, who forwarded it to the list because he thought it appropriate 
(which was fine with me; it just explains why the mail wasn't in the 
form you were expecting).

Well, OK, yes, I (an RDF novice I will add) think it'd be nice if SPARQL 
had GROUP BY support a la SQL.  I had simply assumed it'd been discussed 
and was possibly forthcoming and was asking for update.  Since it seems 
not to be the case, I think it should.

Anyone else agree?
