As the Observer interface for LiveData only has one observe function, why should we write Observer { ... } and not directly a lambda ?
Also, wouldn't it be nice if the parameter of the Observer lambda would take the nullability of the T value from LiveData into account ?

val nonNullable: LiveData<String> = ...
nonNullable.observe(this) { value: String -> ... }
val nullable: LiveData<String?> = ...
nullable.observe(this) { value: String? -> ... }

You can use androidx.lifecycle:lifecycle-livedata-ktx and import androidx.lifecycle.observe function that lets you write lambda directly as someLiveData.observe(viewLifecycleOwner).observe {}
