What about this?

class Array
  def each_leaf(&block)
    each do |x|
      case x
      when Array: x.each_leaf &block
      else block.call x
      end
    end
  end
end

arr = [[1,2], 3, [[4]]]
result = 0
arr.each_leaf{|n| result += n}

puts result

Kind regards,

Serabe

P.D. Sorry for no more explanation, but I'm really tired (2:23 am right now).
