attern
    can include delimiting markers or punctuation, as long as they are
    suppressed, thereby leaving the significant key text.  The value
    pattern can include named results, so that the :class:`Dict` results
    can include named token fields.

    Example::

        text = "shape: SQUARE posn: upper left color: light blue texture: burlap"
        attr_expr = (label + Suppress(':') + OneOrMore(data_word, stop_on=label).set_parse_action(' '.join))
        print(attr_expr[1, ...].parse_string(text).dump())

        attr_label = label
        attr_value = Suppress(':') + OneOrMore(data_word, stop_on=label).set_parse_action(' '.join)

        # similar to Dict, but simpler call format
        result = dict_of(attr_label, attr_value).parse_string(text)
        print(result.dump())
        print(result['shape'])
        print(result.shape)  # object attribute access works too
        print(result.as_dict())

    prints::

        [['shape', 'SQUARE'], ['posn', 'upper left'], ['color', 'light blue'], ['texture', 'burlap']]
        - color: 'light blue'
        - posn: 'upper left'
        - shape: 'SQUARE'
        - texture: 'burlap'
        SQUARE
        SQUARE
        {'color': 'light blue', 'shape': 'SQUARE', 'posn': 'upper left', 'texture': 'burlap'}
    )
