The scope class has an associated global Python + object which controls the Python namespace in which new extension + classes and wrapped functions will be defined as + attributes. Default-constructing a new scope object + binds it to the associated global Python object. Constructing a + scope object with an argument changes the associated + global Python object to the one held by the argument, until the + lifetime of the scope object ends, at which time the + associated global Python object reverts to what it was before the + scope object was constructed.
