Function.toString() omits function name in output

[luckydye]

What version of Bun is running?

1.0.33+9e91e137f

What platform is your computer?

Darwin 23.2.0 arm64 arm

What steps can reproduce the bug?

Run:

echo "function myFunction() {
  console.log('Test function');
  if (true) {
    return 1;
  }
}
console.log('export ' + myFunction.toString());" > test.js && bun test.js

What is the expected behavior?

Expected ouput:

export function myFunction() {
  console.log('Test function');
  if (true) {
    return 1;
  }
}

What do you see instead?

export function() {
  console.log("Test function");
  return 1;
}

Additional information

I came across this issue when trying to run @vitejs/plugin-vue-jsx which relies on Function.toString to include the name for export, like in my example above.
