Finally, a concrete statement.  And patently false.  In Java, you call a
method from a factory that returns an object that implements an interface.
Only the interface is known to you.  You have the source to neither the
factory nor the final class, nor to the interface which it implements.
Please show me (without using the debugger, or some hokey
serialize/unserialize boogums) how to access a private variable in that
object.

In Python, it's simply an assignment.

In any event, this is a collosal waste of time.  But still I feel compelled
to argue these points with you because you are, whether you like it or not,
an authority figure here, and you might want to take the time to distinguish
between agreed technology and your opinion when making statements, because
frankly you're at odds with the rest of the world in many areas.

At least when I spout my scatter-brained opinions, I clearly delineate them
as such.  You declaim your opinions, even when they are diametrically
opposed to conventional wisdom, and state them as if they were fact.  This
is very dangerous for anybody who listens to you and doesn't know better.

One more time: information hiding is an OO concept.  Period.  I didn't say
it.  The guys who invented this stuff did.  Read their works.
