Should the following use rvalues references to stream in insert/extract operators?

19.5.4.1 [syserr.errcode.overview]
20.3.2.2.12 [util.smartptr.shared.io]
99 [facets.examples]
22.9.4 [bitset.operators]
29.4.6 [complex.ops]
Doubled signatures in 31.6 [stream.buffers] for character inserters (ref 31.7.6.3.4 [ostream.inserters.character]) + definition 31.7.6.3.4 [ostream.inserters.character]
28.6.8 [re.submatch]

[ Sophia Antipolis ]

Agree with the idea in the issue, Alisdair to provide wording.

[ Daniel adds 2009-02-14: ]

The proposal given in the paper N2831 apparently resolves this issue.

[ Batavia (2009-05): ]

The cited paper is an earlier version of N2844, which changed the rvalue reference binding rules. That paper includes generic templates operator<< and operator>> that adapt rvalue streams.

We therefore agree with Daniel's observation. Move to ~~NAD Editorial~~Resolved.
