My 2p: I feel just the opposite. Conflating classes (OOP) with
access control is a big mistake in my book, a big mistake made by Java
that we ought to learn from. It leads you to either write really huge
classes, or to have to 'decorate' all your classes with public
declarations. Access control should have its own orthogonal mechanism
-- modules or packages that can consist of one or more classes and can
gather the access control declarations in one spot so they are easily
analyzed, as opposed to scattering them over all the component classes.
