Error: parse compiler const

[SlavaRa]

For example: if i do parse code
package {
import flash.display.Sprite;

/**
 * @author SlavaRa
 */
public class Main extends Sprite {

    public function Main() {
        if(CONFIG::debug) {
            trace("debug");
        } else {
            trace("release");
        }
    }
}

}

i get result:
ERRORS: These files were not written due to source parsing errors:
In D:/projects/fd-dev-as3/./src/Main.as(10) : Unexpected debug

i think that this code can be parsed to

if debug

trace("debug");

else

trace("release");

end
