Namespace Mystery (HELP!)

If you're devious enough, it can be done (warning,
trying to understand how this works may cause
brain explosion):

def spam():
  my_globals = {}
  parrot = 'alive'
  cmd = "global g; g = 42; parrot = 'resting'"
  exec "exec cmd in my_globals, locals()"
  print my_globals['g'], parrot
