is there a way of using `with` when the variable é optional? for instance,
inside a fragment, the `activity` is optional, so can I use something like

```
private fun goToMain() = with(activity) {
            val intent = Intent(this, MainActivity::class.java)
            startActivity(intent)
            finishAffinity()
}
```

You can replace it with `activity?.run { }`

Right, it was discussed before, basically `.run{}` is the equivalent of `with` plus nullable support, so one might think that the usage of `with` is a bit questionable.

<@U0N8HQET0> i guess `with` is more readable

I'm inclined to agree with you. I went through the same process: was using `with` then realised this limitation, then didn't want to mix both for basically the same thing and refactor every time I switch null/nullable... Ended up using `.run` almost everywhere.

An alternative is creating your own function, such as `withOptional` or something
