### Usage

- alternative operators: as an alternative for `^=`

### Example

Run this code

    #include <bitset>
    #include <iostream>

    using bin = std::bitset<8>;

    void show(bin z, const char* s, int n)
    {
        if (n == 0) std::cout << "┌────────────┬──────────┐\n";
        if (n <= 2) std::cout << "│ " <<s<<  " │ " <<z<<" │\n";
        if (n == 2) std::cout << "└────────────┴──────────┘\n";
    }

    int main()
    {
        bin x{"01011010"}; show(x, "x         ", 0);
        bin y{"00111100"}; show(y, "y         ", 1);
        x xor_eq y;        show(x, "x xor_eq y", 2);
    }

Output:

    ┌────────────┬──────────┐
    │ x          │ 01011010 │
    │ y          │ 00111100 │
    │ x xor_eq y │ 01100110 │
    └────────────┴──────────┘
