I still find myself doing something like:

```
if (viewModel.value?.items()?.subItems != null) {
    //Do my thing
}
```

I don't think this is bad because it's straight forward. As long as that statement is not null I want to execute some code. Is there a more idiomatic way of doing this?

```
viewModel.value?.items()?.subItems?.let { //or run, apply, etc..
   //do your thing
}
```

I personally prefer `with`. Feels quite declarative:

```
with(viewModel.value?.items()?.subItems?) {
    map(propertyA)
    println(size)
    //example
}
```

Is there a way to handle the null case using with?  I typically use let because it allows for the elvis operator.

`viewmodel?.value?.items()?.subItems?.let { doThing(it) } ?: handleNullSubItems()`

You could probably do something like this: `private val ViewModel?.subItems: List&lt;SubItemType&gt; get() = value?.items()?.subItems.orEmpty()` and then use a normal if statement (which is more readable imo but it really depends on the situation), also assuming that items being null or empty list is semantically same thing to you

All of these feel like more work to understand than just the if statement. :sob:

Maybe I just don't understand let, run, apply, with...
