I hope the old (perl5) way is still available as well. There are times when parts of the comparison should be done lazily. Consider two objects that have a value for a primary sorting order, but only for those which the value is the same, we fall back to a secondary sort key that is expensive to compute (like maybe calling a database). For these scenarios, specifying the sort comparison will be simpler and cheaper than specifying the sort key. So, we need both, but if we get only one, the Perl5 way is superior. -- Randal L.
