h4>Templated Constructors</h4>
<p>
Templated constructor have the form:
<pre><code>
template&lt;class T&gt;
dataflow_iterator(T start) :
    iterator_adaptor(Base(start))
{}
</code></pre>
When these constructors are applied to our example of above, the following code is generated:
<pre><code>
std::copy(
    insert_linebreaks(
        base64_from_binary(
            transform_width(
                address
            ),
        )
    ),
    insert_linebreaks(
        base64_from_binary(
            transfor
