It was added as a static method because of problems with backwards compatibility when the `domain` field was introduced to `EventEmitter` (https://github.com/joyent/node/issues/5310).\n\nNow that we are somewhat less strict about this and is introducing other new methods (https://github.com/iojs/io.js/commit/2931348372c5670e5d0d3f36ff62f17148f05d3e) on the prototype for `EventEmitter`, maybe we could clean up this api?\n\n(You guys who was involved in this, feel free to correct me on the historical details)\n","author":{"url":"https://github.com/tellnes","@type":"Person","name":"tellnes"},"datePublished":"2015-02-05T23:08:11.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":11},"url":"https://github.com/734/node/issues/734"}
