Subject: Real life use of each_cons? (... follow up)

 Hi there!

(following up the discussion from last year)

 This method actually made my life a lot easier when fitting some data
 to a table. I had tens of pictures and wanted to show them in rows -
three columns each.

 data.each_cons(3) do |column|
  column.each do |picture|
    show picture
  end
 end

 I was playing with indices, modulos and stuff. After refactoring with
 each_cons, the code looked much cleaner.

 cheers!
