> If ?x is used in the body, it does correctly 
> {noformat}
> SELECT (?x+1 AS ?x) { BIND(1 AS ?x) }
> {noformat}
> so this
> {noformat}SELECT ( (?x+1) AS ?x ) {}{noformat} 
> should ideally be a parse error.
> At the moment (3.0.1) it does not and ?x is not set so it's an eval failure with x still not set.
