The example should have used "exec", but there
are problems with that in the new nested-scope
environment, e.g. what should

  x = 17
  exec "x = 42"
  print x

do? The result of the last big argument on
python-dev about this seemed to be that we should
deprecate enough things so that you can't even *try*
to do anything like that.
