__getattr__() is only called if an (Python) instance attribute is not
found via the standard lookup mechanism. __setattr__(), however, is
called for every (Python) instance attribute assignment. To overload
these methods has the potential of causing some trouble and overhead.
In __setattr__() every attribute assignment would need to be checked
against the list of valid SAGA attributes.
