How to define local variables in Vue3's template files

There are situations when you'd like to use local variables in the likes of [Java's Thymeleaf](https://www.thymeleaf.org/doc/tutorials/2.1/usingthymeleaf.html#local-variable), for example. 

```
<li v-if="setting" :key="setting.id" :with="chart = fromSetting(setting)">
  {{ chart.name }}
</li>
```


P.S. This solution only works with template rendering to display data. Passing it to events won't work since it will always pass the latest evaluated value from the loop.
