Just my 2p...
If we are going to be discussing code style (which I think we should) we should - we should have a more general discussion with the whole team.

I personally think this reads well, but that's subjective.

There is also the idea of overriding the prototype object, but then you loose the constructor, which we don't seem to use as we don't use inheritance. Again, this should be down to a team decision, and the code base is now getting big enough that we should start using defined patterns and methodologies.
