If you unpickle though will the results be the same? I suspect they
will be. That should matter most of all (unless you plan to compare
objects' identity based on their pickled version.)
Remember, that by default pickle and cPickle will create a longer
ASCII representation, for a binary representation use a higher pickle
protocol -- 2 instead of 1.
Hope that helps,
