Something like that maybe ?

import std.stdio;
import std.meta;

enum connected = () {
     auto something = AliasSeq!("one", "two", "three");
     string res = "";
     static foreach(item; something) {{
         res ~= item;
     }}
     return res;
}();

void main()
{
     writefln("connected = %s", connected);
}
