Stack from [ghstack](https://github.com/ezyang/ghstack) (oldest at bottom): * #31066 * __->__ #31032 Prior to this PR, we check whether the property load source (e.g. the evaluation of `<base>` in `<base>.property`) is mutable + scoped to determine whether the property load itself is eligible for hoisting. This changes to check the base identifier of the load. - This is needed for the next PR #31066. We want to evaluate whether the base identifier is mutable within the context of the *outermost function*. This is because all LoadLocals and PropertyLoads within a nested function declaration have mutable-ranges within the context of the function, but the base identifier is a context variable. - A side effect is that we no longer infer loads from props / other function arguments as mutable in edge cases (e.g. props escaping out of try-blocks or being assigned to context variables)
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.
