oracle join (+) vs. ( + )

[karsany]

I see, there is support for (+) syntax, but if in the statement "( + )" is instead of "(+)" then the parser throws ParseException. In other words:

The parser is good for this query:

    Select * From dual d1, dual d2 where d1.dummy = d2.dummy(+);

But the parser throws ParseException for this query:

    Select * From dual d1, dual d2 where d1.dummy = d2.dummy( + );
