Prototyping and Iterating

The borrow checker can be slower to prototype with when we just want to solve the problem rather than being distracted by the language, even for more experienced rustaceans.

One user says, "Rust’s complexity regularly slows things down when you’re working on system design/architecture, and regularly makes things faster when you’re implement
