> Slice objects are really meant to be internal structures and not passed around in the user's code. I don't know what they're "meant" to be, but they're certainly not internal. If you implement __getitem__, __setitem__, or __delitem__, then chances are Python is going to be passing slices to your code. That doesn't sound internal to me. Having hashable slices is nice. The repr() workaround has a major drawback in that it makes it difficult to use the extremely useful "indices" method of the slice type.
