Repro steps

1: give react compiler this code

export function MyComponent() {
  return <HelloWorld onClick={() => {
    foo(function bar() {
      if (Math.random() > .5) {
        baz();
      } else {
        qux(bar);
      }
    });
  }} />
}

2: notice the following error

Found 1 error:

Invariant: [InferMutationAliasingEffects] Expected value kind to be initialized

<unknown> bar$5.

   5 |         baz();
   6 |       } else {
>  7 |         qux(bar);
     |             ^^^ this is uninitialized
   8 |       }
   9 |     });
  10 |   }} />
