In the best case, there should be only one standard to learn per language. We hope this results in:
We acknowledge that neutral choices can be arbitrary, but good choices improve readability. As for the arbitrary ones, well, we take the view that we’d rather not expend mental energy thinking about them.
Exceptions to these standards are usually along the lines of “there is already an established local standard”. And that’s great. If someone has already thought about coding style then the last thing we want to do is waste that effort by needlessly changing to another set of standards.
