Don't worry, I'm not singing in this one. Instead, I'm reciting a poem written by "Qi", as part of "The Codeless Code", a collection of fables and koans for software engineers. In Qi's words: "To mark the solemn occasion of the two-hundredth case being entered into the annals of the Temple, I asked the nun Yíwen to prepare for me a long, informative, and heavily-footnoted treatise on the history of the Boolean data type. To my dismay I received this bit of doggerel instead. Many apologies to those of you who came here seeking edification." It can be found here: http://thecodelesscode.com/case/200
