/**
 * SwfdecAsScope:
 * @see_also: #SwfdecAsFrame, #SwfdecAsWith
 *
 * A scope is the abstract base class for the #SwfdecAsWith and #SwfdecAsFrame 
 * classes. It is used to resolve variable references inside ActionScript.
 * Consider the following simple ActionScript code:
 * <informalexample><programlisting>
 * foo = bar;
 * </programlisting></informalexample>
 * The variables foo and bar have to be resolved here, so that the script
 * engine knows, what object to set them on. This is done by walking the scope
 * chain. This chain is build up using With and Frame objects.
