Add dynamic method/instance variable access?

I'm not sure if this issue is implied by the "add reflection" thread here, but I just wanted to be more specific. I want to be able to do something like this

class Model {

  // ... setting instance variables

  Model(Map fields) {
    fields.forEach((k,v) => this[k] = v);
  }

}

It obviously doesn't work, because this doesn't have a []= method. I would be nice to be able to call methods (in this case, setters) dynamically or maybe even set instance variables names dynamically.

Once the reflection system is in place, this will of course be possible (but it won't look like this). At least that is my understanding. I think this is a duplicate of issue #265.
