In Qt 6.10 documentation, qDebug() is now documented as a dedicated macro, separate from the qDebug(const char*, ...) variant.

See

https://doc-snapshots.qt.io/qt6-6.10/qdebug.html#macros

and

https://doc-snapshots.qt.io/qt6-6.10/qtlogging.html#macros

But while the const char variant appears with correct arguments, the streaming operator variants do not show a '()'- although that is part of the macro definition.
