Sorting and something like the <=> operator

This is probably more of a Ruby question than a RoR question.

I need to sort an array of objects in descending order based on a specific attribute. Sorting as follows results in an ascending order:

@items.sort! { |item1, item2|                           item1.value_total <=> item2.value_total}

To order descending, I need to then:

@items.reverse!

I'm wondering if there is an operator similar to <=> that would result in the reverse order? It seems a different operator could net a more efficient algorithm. Or perhaps reverse is not an intensive activity?

Wow, for every good question I ask there are about three horrendous ones. :slight_smile:

I had tried that earlier, but before I had fixed some other issues. Got confused. Clearly that works.
