Update some line notes

* Cletusc mentioned that mongoose has a specific object name syntax so removed those
* Minimally expanded some non-descript identifiers as per previous conversations.
* Inline function using `fn` a bit here... technically in strict mode these should be near the top of the function declaration before any other code. I'm still surprised that V8 doesn't throw an exception on these.
