Subject: Array.shuffle/Array.shuffle!

This works but I can't escape the nagging sense that there's a more
concise approach (for one thing, it looks like there are way too
transient objects to me).

Anyone have a better idea?


class Array

  def shuffle
    t_self = self.dup
    t_size = self.size
    result=[]
    t_size.times { result << t_self.slice!(rand(t_self.size)) }
    result
  end

   def shuffle!
    t_self = self.dup
    t_size = self.size
    self.clear
    t_size.times { self << t_self.slice!(rand(t_self.size)) }
    self
  end

end


Regards...
