I find this notion to be dubious. If a class is so big that, to ensure
the sanity of the class's state, it becomes necessary to give
individual member functions access to individual data members, then
that class has grown too big and needs to be split out into multiple
classes. The only downside is that it is slightly less convenient, as
the outer class has to explicitly expose the functions of the inner
class.
