copysort patch, was RE: [Python-Dev] inline sort option

[Raymond Hettinger]

Did the discussion of a sort() expression get resolved?

The last I remember was that the list.sorted() classmethod had won the
most support because it accepted the broadest range of inputs.

I could live with that though I still prefer the more limited
(list-only) copysort() method.
