```js
match = "424242"
regex = /(42)+?\d{2}\1/g
```

- `/`: `operator` -> `string.regex` (like `"` for regex strings)
- `+?`: `operator.regex`
- `\d`: `string.escape` -> `string.escape.regex`
- `\1`: `keyword.operator.regex` (backreference)
- `/g`: `keyword.regex` -> `keyword.operator.regex`
- `{2}`: `number` -> `number.quantifier.regex`

Release Notes:

  - Improved Regex highlighting
