#Arbitrarily overriding the defaults

The default code formats, input/output methods, and other defaults are a product of community thought and discussion. Don't change them just because you feel like it or disagree with them. They have good reasons for being as they are, some of which are only apparent for specific languages that would otherwise be unusable or cumbersome or require ad-hoc rulings.

Only override the defaults when they don't serve their purpose because of some specific feature of your challenge, and even then think if you can make the challenge accommodate instead.
