Rant title: Encapsulation and access restriction are orthogonal
            concepts.

Rant variant: Python.

Rant summary:

  The concept of privacy existis in Python. Please don't confuse
  privacy with access restriction.

  Python supports encapsulation. Please don't confuse encapsulation
  with access restriction.

  Encapsulation is data abtraction; access restriction is a pain in
  the arse.

Rant body:

... access restriction for the really dense.

If the programmer is too dumb to figure out the name mangling scheme
and work around it, then he (and the project he is working on) has
some serious problems, to the extent that accessing private data when
he shouldn't becomes but a drop in the ocean.
