pair(T1, T2) -> pair<T1, T2>;
(since C++17)

One deduction guide is provided for std::pair to account for the edge cases missed by the implicit deduction guides.

In particular, non-copyable arguments and array to pointer conversion


#include <utility>
int main()
    int a[2], b[3];
    std::pair p{a, b}; // explicit deduction guide is used in this case
