Got deprecated warning with Enum.partition/2,
Enum.split_with/2 instead.
Works great!
Thanks

My mistake :lists.partition/2 still works
updated to this

defmodule Quick do
  import Enum, only: [split_with: 2]
  def sort([]), do: []
  def sort([head|tail]) do
    {pivot, greater_than_head} = split_with(tail, &(&1 <= head))
    sort(pivot) ++ [head] ++ (greater_than_head)
   end

end

big thanks @hauleth
