let t = 1, 'a', "b"in OCaml, parenthesis for tuples are optional and only used to disambiguate.
Type inference can determine the type of the tuple without annotation.

std::tuple<float, std::string, bool> t(2.5f, "foo", false);Strongly typed, can include any primitive or class and be of arbitrary (but fixed) length.
auto entry = tuple!("index", "value", "active")(4, "Hello", true);
Field names can be provided.
entry.index is 4, etc.

a, b, c := 2.5, "hello", make(chan int)a, b, c are strongly typed and could hold the multiple return values of a func.
While a, b, c can most often be used like a tuple, they are technically not a tuple named t.

t = (a, b, c)let t = [2.5, "hello", -1];An Array may hold any list of values.

Elements of type Tuple are strongly typed.
The Default intrinsic will create a variable of type Tuple with all it's members set to their respective default values.
The Default intrinsic will create a variable of type Tuple with all it's members set to their respective default values.
use constant t => (1, 'two', 3.5);This satisfizes the definition of a tuple in that it is fixed length and immutable; however, it probably doesn't provide the speed advantages that a tuple enjoys in other 'strongly typed' languages.
my $tuple = [1, 'Hello World', {foo => 1}];Because of Perls dynamic typing nature, a Tuple is just an Array.
t = tuple('abc', 123, true)t = (2.5, "hello", -1)Tuples are immutable.
They may be created with elements of any type.
