          The output shown is that produced by the default debug actions - custom debug actions can be
          specified using L{setDebugActions}. Prior to attempting
          to match the C{wd} expression, the debugging message C{"Match <exprname> at loc <n>(<line>,<col>)"}
          is shown. Then if the parse succeeds, a C{"Matched"} message is shown, or an C{"Exception raised"}
          message is shown. Also note the use of L{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 C{Word} expression without calling C{setName} is C{"W:(ABCD...)"}.
