I was always wondering why this doesn’t “just work” in D:

```D
enum Color { red, orange }
Color color = orange;
```

This is a major source of frustration when porting from C, where 
enum assignment does work like this (but, unlike in D, enum 
member names must be unique).

Usually D compiler is smart enough to evaluate the type of the 
right-hand of an assignment. But for some reason it’s not the 
case with enums. I was under impression that this is a deliberate 
(although questionable) design to avoid some bugs rather some 
technical limitation.
