<h4>Constructing cons lists</h4>
<p>
A cons list can be constructed from its head and tail. The prototype of the constructor is:
<pre><code>cons(typename tuple_access_traits&lt;head_type&gt;::parameter_type h,
const tail_type&amp; t)
</code></pre>
The traits template for the head parameter selects correct parameter types for different kinds of element types (for reference elements the parameter type equals the element type, for non-reference types the parameter type is a reference to const non-volatile element type).
</p>
<p>
For a one-element cons list the tail argument (<code>null_type</code>) can be omitted.
