<p>The <code>scope</code> class has an associated global Python
object which controls the Python namespace in which new extension
classes and wrapped functions will be defined as
attributes. Default-constructing a new <code>scope</code> object
binds it to the associated global Python object. Constructing a
<code>scope</code> object with an argument changes the associated
global Python object to the one held by the argument, until the
lifetime of the <code>scope</code> object ends, at which time the
associated global Python object reverts to what it was before the
<code>scope</code> object was constructed.</p>
