Sth like:

private inline fun updateRegistrationState(update : RegistrationState.()->RegistrationState){
    registrationState = update(registrationState)
  }

I would like to call it as:
updateRegistrationState { gender = Gender.MALE } instead of updateRegistrationState { copy(gender = Gender.MALE) }

I don’t think so

Why dont you just make RegistrationState mutable ? ie:

private inline fun updateRegistrationState(update : RegistrationState.()->RegistrationState){
    registrationState = registrationState.copy().update()
  }

[Paul Woitaschek]

Because I hate mutability

[spand]

Nothing wrong with mutability in a builder. If you expose RegistrationState elsewhere then maybe have a MutableRegistrationState : RegistrationState only for use in the builder ?
