> The BNF for queries has:
>   <join specification> ::= ON "(" <column reference> "=" <column reference> ")"
> I see no reason to have the parentheses mandatory; for consistency with the syntax of many databases I'd rather have:
>   <join specification> ::= ON ( <column reference> "=" <column reference> | "(" <column reference> "=" <column reference> ")" )
> (And if people want to completely ditch the redundant parentheses I'm all for it as well.)
