起票者: Kenta Murata
ステータス: Open, 優先度: Normal
Target version: 1.9.2
ruby -v: ruby 1.9.2dev (2010-03-15 trunk 26937) [x86_64-darwin10.2.0]

termtter の 464948b77fb335140bcd6e2a76dddc8cac7620a9 版を
ruby 1.9.2dev r26937 で実行すると以下のような例外が出て止まります。

/Users/muraken/src/termtter.git/lib/termtter/client.rb:225:in `legacy_config_support': method `===' called on hidden T_STRING object (0x00000100b0c6f0 flags=0x524805 klass=0x0) (NotImplementedError)
        from /Users/muraken/src/termtter.git/lib/termtter/client.rb:216:in `load_config'
        from /Users/muraken/src/termtter.git/lib/termtter/client.rb:306:in `run'
        from bin/termtter:14:in `<main>'

これは termtter のバグでしょうか？
それとも ruby のバグでしょうか？

以下は、この例外が出た場所でスタックトレースを出してみた結果です。
