I see. No, unfortunately, I am currently not aware of a way to 
make symbol act as type and and value at the same time.

However it is worth noting that you use plenty of excessive 
attributes. Currently it is not a compiler error but makes code 
much harder to read and confusing. For example, "final" has no 
meaning for structs as they can't be inherited from anyway. 
Duplicating immutable is also excessive because it is transitive.
