The reader simply cannot know from just this segment of code.

Other principles articulate common ideas. For these extra general principles, extra in depth and unique guidelines present partial checking.

As at any time, keep in mind that the aim of those naming and layout guidelines is regularity and that aesthetics range immensely.
