" If you've executed a grep/ack command and you have a bunch of stuff in your
" quickfix window, but want to add another grep to it, this could help:
"
"   :Ack ProjectCollaborator
"   :Qfappend Ack UserCollaborator
"
" This will add the new search results to the end of the quickfix list,
" instead of replacing it. You could also put swap the order by using
" :Qfprepend
"

How I would describe quicksort in an imperative way:

def sort(list):
    pivot is midpoint(list)
    left_part is an empty list
    right_part is an empty list

    for every item in the list
        if the item is smaller than the pivot

add(item) to left_part
