+Subclause [[tuple]](tuple "22.4 Tuples") describes the tuple library that provides a tuple type as
+the class template tuple that can be instantiated with any number
+of arguments[.](#1.sentence-1)
+
+Each template argument specifies
+the type of an element in the tuple[.](#1.sentence-2)
+
+Consequently, tuples are
+heterogeneous, fixed-size collections of values[.](#1.sentence-3)
+
+An instantiation of tuple with
+two arguments is similar to an instantiation of pair with the same two arguments[.](#1.sentence-4)
+
+See [[pairs]](pairs "22.3 Pairs")[.](#1.sentence-5)
