Idiom #220 Create a tuple value

Create t consisting of 3 values having different types.

Explain if the elements of t are strongly typed or not.

t = (2.5, "hello", -1)

t = tuple('abc', 123, true)

let t = 1, 'a', "b"

#include <tuple>

std::tuple<float, std::string, bool> t(2.5f, "foo", false);

#include <tuple>

auto t = std::make_tuple(2.5f, std::string("foo"), false);

var t = (2.5f, "foo", true);

import std.typecons;

auto entry = tuple!("index", "value", "active")(4, "Hello", true);

import std.typecons;

auto value = tuple(5, 6.7, "hello");

t := []any{
	2.5,
	"hello",
	make(chan int),
}

a, b, c := 2.5, "hello", make(chan int)

t = (a, b, c)

let t = [2.5, "hello", -1];

record Tuple(Object ... a) {}
Tuple t = new Tuple("abc", 123, true);

record Tuple(int a, String b, boolean c) {}
var t = new Tuple(1, "hello", true);

record Tuple<A, B, C>(A a, B b, C c) {}
Tuple<String, Integer, Boolean> t
    = new Tuple<>("abc", 123, true);

class Tuple {
    String s;
    int i;
    boolean b;
}

val t = Triple(2.5, "foo", true)

type
  Tuple = record
    a: integer;
    b: string;
    c: boolean;
  end;
var
  t: Tuple;
begin
  t := Default(Tuple);
end.

use constant t => (1, 'two', 3.5);

t = [2.5, "hello", -1]

let t = (2.5, "hello", -1);

Dim t = (2.5F, "foo", True)

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