The specification currently says: "It’s a compile-time error if such a mixin application introduces any instance variables. We need to be able to call an implementation specific superclass const constructor of Enum, and a mixin application of a mixin with a field does not make its forwarding constructor const. Currently that’s the only restriction, but if we add further restrictions on mixin applications having const forwarding constructors, those should also apply here." So, it seems to me that there is no exception for final fields.
