The semantics of the operators are actually not as clear as

```d
enum Direction

N = 1, NE, S = 45, SW

Certainly! EnumMembers; can be used. The EnumMembers template
from the std.traits module is used to retrieve all the members of
an enumeration. It generates a tuple containing all the
enumeration values, which can be iterated over using a foreach
loop. In the D programming language, you can use EnumMembers to
iterate over enum values at compile time, which is useful for
generating code based on enum members.
Here’s a simple code example:
```d
enum Days
{
Monday = 1001,
Tuesday = 1010,
Wednesday = 1011,
Thursday = 1100,
Friday = 1101,
Saturday = 1110,
Sunday = 1111
}
import std.traits : EnumMembers;
foreach(day; EnumMembers!Days)
day.writeln(":", cast(int)day);
```
