Test code is total: we require it to always terminate or it's a failure! It also typically has 100% line and branch coverage. I feel way less nervous about refactoring tests, you can always just run them.

It feels like a mature software project is one where bugs require multiple commits to fix. You've hammered out the basic issues, so the remaining issues are often weird interactions between components.

I really like pattern matching in Rust, but I find myself using it less and less. `if let` and `let ... else` require substantially less indentation, and I often use them for Option values. I don't miss this syntactic sugar in OCaml though. Maybe it's just because OCaml has a 2 space indent, unlike Rust's 4 space indent?
