I would like to point out that instructing people does not really work. Besides, other examples like this: if d[x] >= 3: d[x] += 1 don't really work. That's a good point. But then, perhaps PyPy should analyze the eq method and decide whether it's likely to have side effects or not (the answer can be hard-coded for built-in types such as str). Regards Antoine.

Ok. But then how is it valid to have "is" fast-path?
