        The function <code class="computeroutput"><span class="identifier">one_of_equal</span></code>
        is similar to <code class="computeroutput"><span class="identifier">one_of</span></code>, but
        instead of taking a predicate to test the elements of the sequence, it takes
        a value to compare against.
