    The built-in type structseq (used by e.g. os.stat() for the stat
    structure and by the time module for a time tuple) resembles the new
    namedtuple type added to the collections module in 2.6.

    It would be nice if these had at least a common ABC if not a shared
    implementation.

    At the same time I think that in 3.0 we should remove the feature of
    "hidden fields" which is used to have structs that behave like
    fixed-size tuples even though they have a variable number of named
    fields (the list of names varies per platform). We should deprecate the
    use of tuple-unpacking for these (except for the first 6 fields of a
    timetuple, perhaps).
