AngularJS provider return dynamic $get

I am wondering if it is possible or even wanted to have a provider return variables / functions dynamically?

I have been creating a plnkr here.

What I basically trying to do is instead of returning keys in the $get method of the MyLogProvider, I would like to return everything without using keys with it.

So for example I would like to change:

MyLog.keys.auth('This is going to be logged into the app:auth namespace');

To:

MyLog.auth('This is going to be logged into the app:auth namespace');

Therefore I need to change the output of below dynamically by looping over all keys, is this possible?

$get: function() {
  return {
    keys: keys
  }
}
