Integration with Json4s

Would it be possible to have an integration with Json4s? Serializing an enum is trivial:

import enumeratum.EnumEntry
import org.json4s.CustomSerializer

object EnumSerializer extends CustomSerializer[EnumEntry](format => (
    PartialFunction.empty,
    {
      case x: EnumEntry => JString(x.entryName)
    }
  ))

But deserializing is not so easy, the tricky part is to instantiate the correct enum type.

It works, thanks!

I had a look at Circe, and it looks promising. But we have a quite large code base which depends heavily on Json4s, so it will be quite some work to migrate, and we will probably wait for Circe to be a bit more mature.
