Idiom #289 Concatenate two strings

Create the string s by concatenating the strings a and b.

(def s (str a b))

S : constant String := A & B;

#include <iostream>
#include <string>

std::string a{"Hello"};
std::string b{"world"};
auto s = a + b;

string s = String.Concat(a,b);

string s = a + b;

var s = a + b;

var s = '$a$b';

s = a <> b

s = a // b

s := a + b

s = a <> b

s = a ++ b

const s = a + b;

String s = "%s%s".formatted(a, b);

String s = a.concat(b);

String s = a + b;

import java.util.Formatter;

StringBuilder t = new StringBuilder(a);
Formatter f = new Formatter(t);
f.format("%s", b).flush();
String s = t.toString();

val s = a + b

local s = a..b

$s = $a.$b;

s := a + b;

my $s = $a . $b;

s = a + b

s = f'{a}{b}'

s = a + b

let s = a + b;

let s = format!("{}{}", a, b);

s = a & b

Do you know the best way to do this in your language ? New implementation...
