Makes sense!
…sions on no-derived-computation-in-effects Summary: The operands of a function expression are the elements passed as context. This means that it doesn't make sense to record mutations for them. The relevant mutations will happen in the function body, so we need to prevent FunctionExpression type instruction from running the logic for effect mutations. This was also causing some values to depend on themselves in some cases triggering an infinite loop. Also added n invariant to prevent this issue Test Plan: Added fixture test
…ns-in-effects Summary: I missed this conditional messing things up for undefined useState() calls. We should be tracking them. I also missed a test that expect an error was not throwing. Test Plan: Update broken test
