Lazy なオブジェクトの inspect がわかりやすくなった反面、
$VERBOSE な時に警告が出るようです。

$ ruby -ve 'p "".bytes'
ruby 2.0.0dev (2012-03-28 trunk 35155) [x86_64-linux]
-e:1: warning: instance variable receiver not initialized
-e:1: warning: instance variable method not initialized
-e:1: warning: instance variable arguments not initialized
#<Enumerator: "":bytes>
$ ruby -ve 'p [].lazy'
ruby 2.0.0dev (2012-03-28 trunk 35155) [x86_64-linux]
-e:1: warning: instance variable arguments not initialized
#<Enumerator::Lazy: []>

xmpfilter を通す時に警告が表示されてちょっと困ります。

$ xmpfilter <(echo '[].lazy # =>')
[].lazy # => #<Enumerator::Lazy: []> # !> instance variable arguments not initialized

• File no-warn-enum-inspect.patch no-warn-enum-inspect.patch added

これらのインスタンス変数はスクリプト側からは見えないので、
警告は出なくてもよいのではないですかね。そういう方向で
パッチとテストを書いてみたので、見ていただけるとありがたいです。
