Like this:

    _is_text_encoding = True # Assume codecs are text encodings by default

    def __new__(cls, encode, decode, streamreader=None, streamwriter=None,
        incrementalencoder=None, incrementaldecoder=None, name=None,
        _is_text_encoding=None):
        self = tuple.__new__(cls, (encode, decode, streamreader, streamwriter))
        self.name = name
        self.encode = encode
        self.decode = decode
        self.incrementalencoder = incrementalencoder
        self.incrementaldecoder = incrementaldecoder
        self.streamwriter = streamwriter
        self.streamreader = streamreader
        if _is_text_encoding is not None:
            self._is_text_encoding = _is_text_encoding
        return self
