private class MutableStateAdapter<T>(
    private val state: State<T>,
    private val mutate: (T) -> Unit

    override var value: T
        get() = state.value

    override fun component1(): T = value

It does not compile for me :(

This is the error message.

"Inheritance from an interface with '@JvmDefault' members is only allowed with -Xjvm-default option"

And this is the code.
