Is there a way to specify that I want to use boxed version of `val`?

I use DI framework and it finds primitive `boolean` here:

```
class MyPresenter @Inject constructor(val field: Boolean)
```
and fails to generate injector.

One way is to use `val field: java.lang.Boolean`, but it feels a bit dirty and generates a warning

`import java.lang.Boolean as BBoolean` and then use that.

Should Boolean really be used as an injectable? I think you should just wrap that 

If you use spring DI you can use
```
@Configuration
class AppConfig(
@Value("\${my-app.boolean}") private val bool: Boolean)
```

Or you can use nullable var
```
@Configuration
class AppConfif() {
  @Value("\${my-app.boolean}") 
  var: Boolean? = null
}
```
Maybe in your case you could use nullable Boolean?

```
class MyPresenter @Inject constructor(val field: Boolean?)
```

Anyway it should be supported by DI framework. If framework doesn't support constructor injection it may be problem in kotlin with primitives, because in Kotlin all primitives is not null unlike Java
