( self, itemseq )
Add sequence of elements to end of ParseResults list of elements.

        Example::
            patt = OneOrMore(Word(alphas))
            
            # use a parse action to append the reverse of the matched strings, to make a palindrome

                tokens.extend(reversed([t[::-1] for t in tokens]))
                return ''.join(tokens)
            print(patt.addParseAction(make_palindrome).parseString("lskdj sdlkjf lksd")) # -> 'lskdjsdlkjflksddsklfjkldsjdksl'
