> How many refactorings per time unit could a smart coder do in both ecosystems? I've found that refactors are more involved in Rust (because of some "viral" features that require changing code in a lot of places, adding lifetimes to a type being the most obvious example) requiring more effort from the developer, but that after handling the complaints from the compiler the resulting code is usually properly ported to the new design. This has not been my experience in other languages, particularly dynamically typed ones. It is partially helped by some design patterns that are prevalent in Rust libraries, like typed builders or more complex trait bounds that ensure correct usage of the exposed APIs.
