Allow clearer code

#28 (comment)

This PR allows clear code to be written in this project.

I'm against diverging from idiomatic Rust.

• Anyone who's proficient in Rust will find this very strange and jarring, especially clippy::needless_return
• If we stick to the clippy defaults we can skip endless debates driven by opinions and preferences
• @bengl chose clippy::pedantic for a reason so I doubt this change would ever make it upstream

Functions should be clear in their return statements.

I also agree, we should aim to stick with the clippy defaults as much as possible.

This also makes it easier for LLMs to navigate and reason through the codebase, which I think is important.
