Attributes with DLUNTU (double leading underscore, no trailing
underscores) are treated as private attributes, and Python munges
their names. E.g. self.__privatemeth() Use these when you definitely
don't want subclasses to access or override them (Python doesn't
actually /enforce/ any access control -- remember we're all consenting
adults :).
My own personal convention is to use SLUNTU (single leading ...) when
I want attributes that are part of the `protected' interface of a
class. E.g. self._override_this()
DLUDTU (double leading ... double trailing), e.g. self.__init__() are
reserved for Python's use.
