The comma isn't terribly important, because QDebug will add spaces. However, it will add blank lines which are NOT wanted if qDebug() is called multiple times. Nor is using a scratch variable really an option, because that would require adding an explicit scope to make the QDebug instance destruct at the right place. -- Matthew -- --- You received this message because you are subscribed to the Google Groups "ISO C++ Standard - Future Proposals" group.
