There is a convention in Google (and elsewhere) to mark data member fields with a trailing underscore in their name. This convention makes it easy to identify field accesses, which helps avoid performance problems (unnecessary reloads) and correctness problems (missing reloads in the presence of aliasing). -- Lawrence Crowl
