If you have a ref that the compiler doesn't know is a ref (say, a value returned from a custom hook) and try to assign its `.current = ...`, we currently fail with a generic error that hook return values are not mutable. However, an assignment to `.current` specifically is a very strong hint that the value is likely to be a ref. So in this PR, we track the reason for the mutation and if it ends up being an error, we use it to show an additional hint to the user. See the fixture for an example of the message.
React Compiler
React Compiler is a compiler that optimizes React applications, ensuring that only the minimal parts of components and hooks will re-render when state changes. The compiler also validates that components and hooks follow the Rules of React.
More information about the design and architecture of the compiler are covered in the Design Goals.
More information about developing the compiler itself is covered in the Development Guide.
