enum-faux-constructor-consumer-pattern

Using a Consumer pattern vs. a constructor to populate an Enum instance.  Handy if you 
have a good number of fields and don't want long argument lists.  Or if you need to do 
some processing/method calling.

final fields would cause issues and would need to be done via a constructor without a callback.

  public enum SomeEnum {
        A((c)->{c.someField="A";}),
        B((c)->{c.lotsMoreFields="B";}),
        /*Syntax error
        C(null) {
            this.someField="a";
        }*/
        ;
        
        SomeEnum(Consumer<SomeEnum> c) {
            c.accept(this);
        }
        String someField;
        String lotsMoreFields;
    }
