You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: compress.rb
    path of file: ./repos/minitest/lib/minitest
    
    the code of the file until where you have to start completion: module Minitest
  ##
  # Compresses backtraces.

  module Compress

    ##
    # Takes a backtra
    
    def compress orig
      ary = orig

      eswo = ->(ary, n, off) { # each_slice_with_offset
        if off.zero? then
          ary.each_slice n
        else
          # [ ...off... [...n...] [...n...] ... ]
          front, back = ary.take(off), ary.drop(off)
          [front].chain back.each_slice n
        end
