__(...) with locale specified comes to an error

[kamikat]

When I use __(...) with specified locale

i18n.__({phrase: 'Have you ever met %s?', locale: 'zh_CN'}, 'Ted');

Error occurred

TypeError: Object #<Object> has no method 'substring'

Am I misunderstanding the document? or, shall I use the latest version from github instead of a package from npm?

Edit

Found that code in package from npm for __(...)

i18n.__ = function i18nTranslate(phrase) {
  // get translated message with locale from scope (deprecated) or object
  var msg = translate(getLocaleFromObject(this), phrase);

  // if we have extra arguments with strings to get replaced,
  // an additional substition injects those strings afterwards
  if (arguments.length > 1) {
    msg = vsprintf(msg, Array.prototype.slice.call(arguments, 1));
  }
  return msg;
};

and the package.json file

{
  "name": "i18n",
  "description": "lightweight simple translation module with dynamic json storage",
  "version": "0.4.0",
  "homepage": "http://github.com/mashpie/i18n-node",
  "repository": {
    "type": "git",
    "url": "http://github.com/mashpie/i18n-node.git"
  },  
  "author": {
    "name": "Marcus Spiegel",
    "email": "marcus.spiegel@gmail.com"
  },  
  "main": "./index",
  "keywords": [
    "template",
    "i18n",
    "l10n"
  ],  
  ...
}

Maybe the package on NPM is broken?

npm version is quite outdated. Shame on me, I planed to release some more features to npm earlier. Time passed and I will publish current git version on friday after a a last review.
