+// function (see bottom of file) sets TriggerError. Then, at the end of each
+// production in the grammer we use CHECK_FOR_ERROR which will invoke YYERROR
+// (a goto) to put YACC in error state. Furthermore, several calls to
+// GenerateError are made from inside productions and they must simulate the
+// previous exception behavior by exiting the production immediately. We have
