I'm not sure if there is a better way, but isInstanceOf (std.traits) seems to work with a static foreach and a static if.

template Qwerty(Values...)
{
    static foreach (value; Values)
    {
        static if (!isInstanceOf!(Qaz, value))
        {
            static assert(0, "Values are not Qaz only ...");
        }
    }

    // ...
}

Thank you everybody!
