The double-underscore name mangling can be used for this.  I wasn't
aware anyone was pussy-footing; I've always thought it has been very
clear that the Python community in general has no interest in adding
explicit access control (beyond the double-underscore mangling trick as
a tip of the hat to conventional practice anyway).

Explicit is better than implicit.  Moreover, since Python can have both
bound and unbound methods, whether or not the self parameter is there
really can make a difference.  Having a totally transparent self
parameter would throw a monkey wrench into things.
