Jón's approach (the last version of his message), usually cleaner and
more concise, is called point-free and is quite common in functional
programming. It can be a bit confusing to newcomers, though, since
part of the function's arguments do not appear explicitly in the
expressions' body (as the list to be matched and modified in your
example). 

You can read something more about this style here:

Hope this helps.
