There are some cases when I need to do reversed sorting. While I could pass in a comparer function that flips the result
(sort #(compare %2 %1) coll), it takes a second before realizing the collection is being reversed.
It would be nice to have a couple functions that did this in a more declarative manner (function names up for suggestions).
"Same as sort, but reversed."
([coll] (rsort compare coll))
([comp coll] (sort #(comp %2 %1) coll)))
"Same as sort-by, but reversed."
([keyfn coll] (rsort-by keyfn compare coll))
([keyfn comp coll] (sort-by keyfn #(comp %2 %1) coll)))
I wound up adding these to a shared library for my projects, but it would be great to have something like this part of Clojure's core library (more selfishly, so that I don't need to require/namespace these functions in my projects).
