Q_INVOKABLE and namespaces

Namespace name has to be explicitly used for QML compatibility, which is especially painful because there is no compile-time check for that.

The earlier bug was resolved by documenting the issue, but it turns out that the section If a C++ class which defines a QML type is declared inside a namespace … disappeared, when registercpptypes.qdoc was moved to definetypes.qdoc.

Is there any chance to make Q_INVOKABLE compatible with C++ namespaces or compile-time check the type or at least re-document the issue?
