01The signal

The report, exactly as it was filed.

Nothing paraphrased or cleaned up. The mess is the thing under test.

Can `exclude` option support function parameter?

In my case

```js
const obj = { '_name': true }
console.log(camelcaseKeys(obj)); // { name: true }
```

but I don't want to lose leading `_` in `_name`, how can I achieve it? 

Thanks

02What counts as reproducing it

The bar, written down before the run.

expected.reportedFailurecommitted with the case
Symptom
camelcaseKeys(({ '_name': true })) produces { name: true }; the fix makes it produce { _name: true }.
Expression
camelcaseKeys(({ '_name': true }))
Reported output
{ name: true }
Where that came from
Read mechanically from the report's fenced code, SAME_LINE form: `console.log(camelcaseKeys(obj)); // { name: true }`.

03What happened

The live run reproduced the reported failure.
