split dies when using a transform function that returns an object

[kevzettler]

per the readme I should beable to pass a function to split which returns an object ( like JSON.parse ) and then get a stream of objects.

Doing this I get an error

function splitHandler(){
  return {test: true};
}

  var stream = fs.createReadStream(file_path)
                 .pipe(zlib.createGunzip())
                 .pipe(split(splitHandler))
                 .pipe(process.stdout)

net.js:614
    throw new TypeError('invalid data');
          ^

    at write (_stream_readable.js:585:24)

if I change the splitHandler to

function splitHandler(){
  return "derp";
}

and return a string it works

the problem is that process.stdout can only accept buffers or strings, and you are passing it objects. if you do .on('data', console.log) that will work, or else add a stream (like require('JSONStream').stringify() that turns a stream of objects into a stream of bytes.
