Declaring a valarray of references?

[xuinkrbin]

Is it permissible to declare, for example, `std::valarray<int&>`? If so, how do I initialize such if the `valarray` is a class member?

No

You can use reference_wrapper to achieve same result

std::reference_wrapper<> does not satisfy the requirements of a numeric type.
