In #32416, @michaelfaith discovered that https://github.com/facebook/react/blob/029e8bd618af23fbdd9efdac565ad81f7d4640d8/scripts/jest/setupTests.js#L82 would fail on the merged compiler eslint rule. Upon further investigation I discovered that our CompilerError implementation doesn't play nicely with Reflect, so `Reflect.construct` would fail as `.toString` would error: ``` TypeError: Cannot read properties of undefined (reading 'map') at _CompilerError.toString (/Users/.../code/react/node_modules/babel-plugin-react-compiler/src/CompilerError.ts:200:25) at _CompilerError.get message [as message] (/Users/.../code/react/node_modules/babel-plugin-react-compiler/src/CompilerError.ts:194:17) at Object.construct (/Users/.../code/react/scripts/jest/setupTests.js:153:52) ``` I tested this fix using my local copy of the built babel-plugin-react-compiler to verify that this fixes those tests.
