Over-organization of code is no good

run.js

var messages = require('./src');

// do this

module.exports = messages.extract()
  .tap(function (messages) {
    console.log('Retrieved %d messages', messages.length);
  })
  .then(messages.transform)
  .done(messages.load);

// this is silly

function logLength (messages) {
  console.log('Retrieved %d messages', messages.length);
}

module.exports = messages.extract()
  .tap(logLength)
  .then(messages.transform)
  .done(messages.load);
