そうやって dump すると、dump できないものが入っていたときに
dump 不能になります。

% ./ruby -ve '
class C
  def initialize
    @a = 1
    @cache = STDIN
  end

  def marshal_dump
    [@a]
  end

  def marshal_load(arg)
    @a = arg[0]
  end
end
p Marshal.dump(C.new)
'
ruby 1.9.2dev (2009-12-06 trunk 26025) [i686-linux]
-e:16:in `dump': can't dump IO (TypeError)
        from -e:16:in `<main>'

以前、[ruby-dev:21475] でも指摘したことがありますが。
