By siroky:

AnyVal isn't a good chice, because String isn't AnyVal and we surely want string parameters. I think we were talking about the conversions and agreed, that the only sensible conversions are only Parameter -> String and String -> Parameter. Also I'd make the ParameterInstance immutable by getting rid of all set* methods and making value a val. String value is redundant because there already is the method toString :)
