Looks like this was fixed in 3.3 in the commit 72890:a22d94547570 Should this 
issue be closed?

Nick Coghlan  added the comment:

Note that one of the reasons for the slightly wishy-washy phrasing in
the docs is to give other implementations a bit more freedom in the way
way they handle these error cases.

Agreed that the main reason is the one Antoine gave though - the
ValueError is looking at things from the point of view that the program
passed in a closed file object when an open one was needed.

I agree with that. It probably needs someone to shepherd the idea to
python-dev so as to get it accepted.

Antoine Pitrou  added the comment:

I think we raise ValueError because that's already what 2.x does with
plain file objects. Also, it's true that it's a programming error (using
a closed file) and not really an "IO error".

Simplest would be to fix the docs for the io module, IMHO.

Should all these ValueErrors be turned into IOErrors?
