By *current definition* they are unordered. The proposal is to add ordering.

No it wouldn't, that would be backwards incompatible. You could check 
order equivalence with:

     list(set1) == list(set2)

Note that I don't know what happened to the proposal or if it still 
stands any chance of inclusion. If it is implemented it will be done in 
a backwards compatible way.



May you do good and not evil
May you find forgiveness for yourself and forgive others
May you share freely, never taking more than you give.
