Improving Scala sorting DSL

Today I encountered an annoying lacking in Scala list sorting support. I just wanted to sort my list by using different fields, some causing an ascending order others causing a descending order.

Well, everything went happily (though with ugly syntax) with Scala´s List.sortBy and unary minus operators... until I needed to perform mixed ascending/descending sorts with strings. Not so easy to implement elegantly.

I tried to google answers but didn't find any useful results. That´s why I decided to make my own syntax by using generics, Ordered trait inheritance and Scala´s implicit Ordering support. I ended up making the following implementation:

Now I can sort my collections (at least in Scala 2.10) with neat syntax:
myList.sortBy(v => (asc(v.mem1), desc(v.mem2), ...))

Syntax should work with all classes having Scala Ordering trait implemented (at least all built-in basic types in Scala). Here is a working example how to use the DSL:

I hope this post helps. Happy sorting!
