This unscoped enums is one of the worst features in C/C++, imho. 
I loved when I switch to languages that the enum got its scopre 
but D you got both, you can also do:

```D
enum A = 0;
enum B = 1;
// ...
```

if you dislike to set their initial values manually, I think you 
can write a template function to create enum values
