1. There is no special requirements for place where this code should be placed right?

Copy code

@instance(User::class)
interface UserEqInstance : Eq<User> {
    override fun eqv(a: User, b: User): Boolean = a == b
}

2. And model that we've created typeclass for should include empty companion

companion object

to unlock ability for companion's object extensions functions?
