Support evolving the type with assignments for expando object

I use a similar module pattern in an application I'm working on, and the lack of IntelliSense/definitions for those has been an issue for me as well.

Mine follow this basic pattern:

module.exports = function(x, y, z) {
  var exports = {};
  exports.method = function() {
    // Something that might use x, y, or z
  };
  return exports;
}

Would it be possible to do something like include an option in the jsconfig.json file to specify a property name or list of names to track when determining module exports?

Maybe something like this?

{
  "moduleOptions": {
    "exportProperty": ["exports", "this"]
  }
}

From @mhegazy (here):

@abgivant, this pattern is actually an easier one to support, we already have plans to do so on the future. it is a general construction patter that is common in JS.
the this one is a bit more tricky though.

From @abgivant (here):

@mhegazy Ah cool. Is that part of the "expando" discussion, or is there a more specific feature in the works for things like that?
