I am actually glad, in a sense, that it was not casual whim. ;-) I do not like the change, since it moves streams back further away from Python's sequence model, but I withdraw the request for reversion in 3.1.3.

I will add further comments on the docs to the issue.

What it does teach us is that Python 3.1 sees some real use,

It is an odd 'coincidence' that the method changed was one of the only two stdlib methods I have used so far used directly. But with enough users, such happens.

What it teaches me is that before I install another release, I should, as planned, automate the running of all module tests together so I can easily test everything before and after a new installation.

When I do release sample chapters and code, I will try to remember to specify the version and platform I tested with.

we have entered a phase where backwards compatibility will become as important as it was in the 2.x line.

I have assumed that there might be a few stdlib API tweeks in 3.2 -- and that they would be well announced.
