I still find myself typing , between select expressions, but you can put that down to SQL-induced brain damage.
BIND(expr1 AS ?x, expr2 AS ?y) without SELECT expr1 AS ?x, expr2 AS ?y would seem strange (and GROUP/ORDER BY etc).
BIND(expr1 AS ?x) BIND(expr2 AS ?y) with SELECT (expr1 AS ?x) (expr2 AS ?y) seems OK, given that the alternative is parser nastiness.
