<h2><a name="introduction"></a>Introduction</h2>
<p>Exposes a <a href=
"ObjectWrapper.html#TypeWrapper-concept">TypeWrapper</a> for the Python
<a href=
"http://www.python.org/doc/current/lib/typesseq-mutable.html">list</a>
type.</p>
<h2><a name="classes"></a>Classes</h2>
<h3><a name="list-spec"></a>Class <code>list</code></h3>
<p>Exposes the <a href=
"http://www.python.org/doc/current/lib/typesseq-mutable.html">mapping
protocol</a> of Python's built-in <code>list</code> type. The semantics
of the constructors and member functions defined below can be fully
understood by reading the <a href=
"ObjectWrapper.html#TypeWrapper-concept">TypeWrapper</a> concept
definition. Since <code>list</code> is publicly derived from <code><a
href="object.html#object-spec">object</a></code>, the public object
interface applies to <code>list</code> instances as well.</p>
