Hi everyone. I found a weird compiler behavior. Here is the row:
`attrs.caption = state.toBeDeleted?.asDynamic()["name"].toString()`
I'm expecting that if `state.toBeDeleted` is `null`, the rest of row will not be invoked, and `null` will be the value of the whole expression. But this row is compiled into:
```$receiver.attrs.caption = ((tmp$ = this$Content.state.toBeDeleted) != null ? tmp$ : null)['name'].toString();```
And the result is `Cannot read property 'name' of null`. Am I misunderstanding something?

Are the extension functions being invoked even on `null` values?

Try this: 
```
attrs.caption = state.toBeDeleted.asDynamic()?.`name`?.toString()
```

`asDynamic` is an extension function to `Any?`, so it will work with `null` receiver

`dynamic` is already nullable, so `null?.asDynamic()` should be the same as `null.asDynamic()`. Both expressions have type `dynamic`. Which is why the compiler didn't complain about the `["name"]` being applied to a nullable receiver
