I was adding __all__ to the random module and I noticed this very unpythonic example in the module docstring:
>>> g = Random(42) # arbitrary >>> g.random() 0.25420336316883324 >>> g.jumpahead(6953607871644L - 1) # move *back* one >>> g.random() 0.25420336316883324
Did you miss the sentence preceding the example, starting "Just for fun"?
In that vein, the example isn't compatible with doctest, is it?
