Is this general rules documeted somewhere? My impression is that readers
of the documentation will treat arguments as keyword arguments unless
this is explicitly contradicted. The reason for this is that when they learn
about writing functions, parameters can be used as keuword arguments by
default.

So I don't think you can fault the readers for treating the
documentation as if it is talking about python functions.
