<note>
<simpara>
When exporting an object, <function>var_export</function> does not check
whether <link linkend="object.set-state">__set_state()</link> is
implemented by the object's class, so re-importing such objects will fail,
if __set_state() is not implemented. Particularly, this affects some
internal classes.
</simpara>
<simpara>
It is the responsibility of the programmer to verify that only objects will
be re-imported, whose class implements __set_state().
