Set literals need to be backported.

I'm going to defer this to 2.7.

Here is a patch for backporting set literals to the trunk.

Guido, I thought you had decided for this to just be a 3.x feature.

Alex, if this goes forward, were you also going to change the repr() for
sets and the corresponding pprint code?  Are set comprehensions on the
radar screen also.  IMO, these all go hand in hand.

I think we should keep the repr() of sets as is to avoid breaking any
code. And yes, I plan to port set comprehensions along with dict

Raymond, I know you see this differently, but personally I don't see a
problem with 2.7 getting additional backports of 3.x features, as long
as they are backwards compatible. While personally I wouldn't spend
effort on this particular backport, I don't see a problem when someone
volunteers a patch. In this specific case, I am fine with accepting set
literals and set comprehensions as new syntax. I do agree that repr()
needs to be kept the same as it was under 2.6.

These all seem fine to me.  Was just checking in because I thought you
had previously pronounced otherwise.

If there are no objections, I will commit this patch later this week.
