Yepp, and I just found my tools for it. I almost forgot about 
those.

```d
enum EnumMemberNames(T) = is(T==enum) ? [__traits(allMembers, T)] 
: [];
enum EnumAssocArray(alias T) = /+keys = enumMember.text, values = 
enumMember+/
((){ T[string] o; foreach(i, name; EnumMemberNames!T) o[name] = 
[EnumMembers!T][i]; return o; })(); ```
```

I only create the AA if it is needed in runtime.

This way the .exe file only contains the enum member names as 
separate zero terminated string literals. All strings are aligned 
to 16 bytes.

Anyways, the most important is to know what's going under the 
hood. Thx!
