I seem to remember having this exact same frustration when I used pickle and shelve 15 years ago. I had hoped to have another way around this. I spent over a decade trying to make an XML-based database work, in part because of this limitation. Some days I get so frustrated I think the only data structure I should ever use is a dictionary. I suppose to make this sort of thing work, I should look at creating custom json encoders and decoders. Thanks, Josh -- https://mail.python.org/mailman/listinfo/python-list
