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.

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.

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