See comments in code. The idea is that rather than immediately processing function expression effects when declaring the function, we record Capture effects for context variables that may be captured/mutated in the function. Then, transitive mutations of the function value itself will extend the range of these values via the normal captured value comutation inference established earlier in the stack (if capture a -> b, then transitiveMutate(b) => mutate(a)). So capture contextVar -> function and transitiveMutate(function) => mutate(contextVar). [ghstack-poisoned]
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.
