How does the example in README show the use of optional_ref

Hi, it is a bit unclear why the example in readme show the use of optional_ref.

The example in question is as follows:

#include <Beman/Optional26/optional.hpp>
...

{
    // Empty optional example.
    std::optional<int>             std_empty_opt;
    beman::optional26::optional<int> beman_empty_opt;
    assert(!std_empty_opt.has_value() &&
            !beman_empty_opt.has_value()); // or assert(!std_empty_opt && !beman_empty_opt);
    std::cout << "std_vs_beman: .has_value() matches?: "
              << (std_empty_opt.has_value() == beman_empty_opt.has_value() ? "yes" : "no") << "\n";
}

{
    // Optional with value example.
    std::optional<int>             std_opt   = 26;
    beman::optional26::optional<int> beman_opt = 26;
    assert(std_opt.has_value() && beman_opt.has_value()); // or assert(std_opt && beman_opt);
    assert(std_opt.value() == beman_opt.value());         // or assert(*std_opt == *beman_opt);
    std::cout << "std_vs_beman: .value() matches?: " << (std_opt.value() == beman_opt.value() ? "yes" : "no")
              << "\n";
}

The values are assigned as values, and the template type of optional in the example is all int, is int& intended to be here instead?

This is just the basic optional use, even before adding the iterator support added for 26.

okay! Thanks for the clarification!
