The text explores the challenges of maintaining consistency in large codebases when using expressive programming languages, exemplified by Scala and C++, which allow for diverse coding styles and can lead to fragmented codebases akin to a city with different dialects. It argues that while style guides can help, they are not sufficient on their own, and proposes the need for a "Style Czar" in language communities to establish evolving standards and guide developers towards a cohesive coding style. By offering a centralized standard, similar to Python's PEP 8, the aim is to reduce fragmentation and create a more uniform codebase, balancing expressiveness with clarity and maintainability. The author emphasizes the importance of language creators in facilitating this process by setting clear guidelines and fostering a dialogue within the community to converge on best practices, thus ensuring that as languages evolve, developers have a consistent framework to follow.
