For better readability, define it in a library. And if it's
defined in a library, well, you might want to write the
implementation in a readable way... :}

 module Enumerable
   def group_by_size(size)
     res         = []

     each_with_index do |o, n|
       res << [] if n%size == 0

       res[-1] << o
     end

     res
   end
 end

 a       = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
 b       = a.group_by_size(3)

 p a
 p b
