Hello,
I have a enum:

enum Type : string
{
    One = "Q1",
    Two = "W2",
    Three = "R3"
}

I want to concat it in compile-time:

enum result = doConcat!Type();

And get this result:

writeln(result); // output: "Q1 W2 R3"

Delimiter here is space symbol.
How do do it?

I think you just need to use the concatenation operator `~`.

enum Type : string
{
    One = "Q1",
    Two = "W2",
    Three = "R3"
}

enum concatenation = Type.One ~ " " ~ Type.Two ~ " " ~ Type.Three;

void main()
{
    import std.stdio: writeln;
    writeln(concatenation);
}
