Hello,
I have an Enum to represent possible Options for a selectList
e.g
enum options {
  blueish="Blue",
  redish ="Red"
}
and I want the List-Entrys to say
"blueish" or "redish".
the value send to the app should be
"Blue" or "Red".
I can use __traits(allMembers,Enum)
for the identifiers, but how do I get the Values ?

import std.stdio;

enum Options {
  blueish="Blue",
  redish ="Red"
}

void main() {
        foreach(m; __traits(allMembers, Options)) {
                writeln(m);     
                writeln(cast(string)__traits(getMember, Options, m));   
        }
}

The cast forces it to grab the value. Note where Options values 
are of type string. Its the same as explicitly saying enum T : 
string {.
