               Example:
               A slot with the signature

               that will be called with the concrete instance as first argument.
               So in Python you can now e.g. call
               \code
               someWidget.doSomething(12)

               of Qt classes callable by forwarding them with such decorator slots
               or to make CPP classes (which are not derived from QObject) callable from Python.
