Data.List should have a takeLastN function
A natural compliment to the take
function that instead takes n
elements from the end of the list rather than from the start would be very useful.
I'm surprised it's not defined in base because it seems to be a common operation that is not trivial to define in an efficient way. See http://www.joachim-breitner.de/blog/600-On_taking_the_last_n_elements_of_a_list
