is there an away to avoid the assertion operator to make the value type not null on the following case?

```
if (key in map) {
        val value = map[key]!!
    }
```

If I remove the assertion operator, the type of the `value` will be `?`

```if (key in map) {
    val value = map.getValue(key)
}```
or
```val value = map[key]
if (value != null) {
    // ...
}```

Cool, I didn't knew about the `getValue` method. It works like a charm here. Thanks :smiley:

Also to make it more explicit with custom error message:
```val value = map[key] ?: error("My custom error")```
