The former is possible but that latter is not: If the object is pickled as a tuple, it will always be unpickled as a simple tuple. To customize unpickling, the serialized data must include the name of the class to use, and that class will never exist in earlier Python versions. I don't think there's a way around this. However, I find Raymond's note very convincing, in that we should likely not let the unpickling issue get in the way of this improvement: > FWIW, most things in Python that return a structseq previously returned a > tuple (for example, time.localtime() and sys.version_info). > > This is not an unprecedented upgrade to improve the repr and provide access > by field name in addition to positional access. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue24416> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
