I'm -1 on adding these to __builtin__.  They are just distractors and
have almost no use in real Python programs.  Worse, if you do use them,
then you are likely to be programming badly -- we don't want to
encourage that.

Also, I take some of these, such as dictproxy and cell, to be
implementation details that are subject to change.  Adding them to
__builtin__ would unnecessarily immortalize them.

Even if Guido were suffering from time machine induced hallucinations
that day, he still knew better than to go a full +1.
