Re: [sage-devel] Sorting strings and integers

This does seem to be new. In Sage 7.2 (just one that I had handy), sage: sorted([1,2,'a']) [1, 2, 'a'] sage: sorted([1r,2r,'a']) [1, 2, 'a'] This isn't that surprising, since the semantics of comparison have been changing because of the upcoming switch to python 3. But I think that Sage integers
