object State extends State

sealed abstract class State extends Enumeration("created", "destroyed") {          
  type State = Value
  val Created, Destroyed = Value    
}

class Thing extends Record[Thing] {
 def meta = Thing    
 object state extends EnumField(this, State, State.Created) 
}

object Thing extends Thing with MetaRecord[Thing]

object Test {         
    
  def switch(state: State#Value) = 
    if(state == State.Created) State.Destroyed else State.Created
  
  val thing = Thing.createRecord      
  thing.state.set(State.Created)
      
  switch(thing.state.is) == switch(State.Destroyed)
}
