Description

Assigning a localized name for enum values is rather challenging with the current Qute API.
It would be helpful to be able to set part of the key as the first parameter of the message method:

Implementation ideas

public enum 
MyEnum {
  ON, OFF, UNDEFINED
}

@MessageBundle 
public interface AppMessages {

    @Message 
    String displayName(MyEnum name);

}

Then the localized file could look like:

# This comment is ignored
displayName.ON=On
displayName.OFF=Off
displayName.UNDEFINED=Undefined

We could add a new annotation for the parameter to make it explicit that it is part of the key:

public interface AppMessages {

    @Message 
    String displayName(@MessageKey MyEnum name);

}

if we want to be able to provide the message in the @message annotation, we could make it repeatable:

public interface AppMessages {

    @Message(key="ON", value="On")
    @Message(key="OFF", value="Off")
    @Message(key="UNDEFINED", value="Undefined")
    String displayName(@MessageKey MyEnum name);

}

or we could just prevent to set the message if MessageKey is present ?
