          The output shown is that produced by the default debug actions - custom debug actions can be
          specified using :class:`setDebugActions`. Prior to attempting
          to match the ``wd`` expression, the debugging message ``"Match <exprname> at loc <n>(<line>,<col>)"``
          is shown. Then if the parse succeeds, a ``"Matched"`` message is shown, or an ``"Exception raised"``
          message is shown. Also note the use of :class:`setName` to assign a human-readable name to the expression,
          which makes debugging and exception messages easier to understand - for instance, the default
          name created for the :class:`Word` expression without calling ``setName`` is ``"W:(ABCD...)"``.
