E.g.,

```D
enum expandEnum(EnumType, string fqnEnumType = EnumType.stringof) 
= (){
     string expandEnum;
     foreach(m;__traits(allMembers, EnumType)) {
         expandEnum ~= "alias " ~ m ~ " = " ~ fqnEnumType ~ "." ~ 
m ~ ";";
     }
     return expandEnum;
}();

enum Color {
     red,
     green,
     blue,
     yellow,
     orange,
     black,
     white,
}
mixin(expandEnum!Color);

void main() {
     auto c = green;
     writeln(c);
}
```
