<https://reviews.apache.org/r/53252/#comment235026>

    `std::set` already defines a constructor taking a range, so I'd suggest not reimplementing it here, but instead to simply inherit the base class' constructors,
    
        using std::unordered_set<Elem, Hash, Equal>::unordered_set;
        
    Note that this makes the constructor taking an `std::initializer_list` redundant, so it should be removed.
        
    Note that this would allow us to simplify existing constructors with even less typing, e.g.,
    
        hashset(const std::set& set) : hashset(set.begin(), set.end()) {}
        
    and similar.
