new X().bar(); is a syntax error?

[Robert Fraser]

I think it might create a parsing ambiguity. Since you can refer to inner clases by prefixing them with the name of the object or type, there's no way to tell during the syntactic pass whether it's a qualified type name or a call expression. You can do it in java/C# because you can't omit the trailing parentheses at the end of the new expression, so once it hits a closing parenthesis, the parser knows that's the end of the new expression.
