According to the C++ documentation

https://doc.qt.io/archives/qt-5.12/qstandarditemmodel.html#headerData

... it takes 2 positional args (section, orientation) and 1 keyword arg
(role).  If I call it with the 2 positional args, I get a traceback saying

TypeError: headerData() missing 1 required positional argument: 'role'

Did pyqt define the 'role' arg as positional?  And if so, why?
