Once the\nfunction is called for the first time the return value of the original\nfunction is saved in `fn.value` and subsequent calls will continue to\nreturn this value.\n\n```javascript\nvar once = require('once')\n\nfunction load (cb) {\n cb = once(cb)\n var stream = createStream()\n stream.once('data', cb)\n stream.once('end', function () {\n if (!cb.called) cb(new Error('not found'))\n })\n}\n```\n",
