Content
Patch # 408326 was designed to make assignment to d[:] an error where d is a dictionary. See discussion starting at http://mail.python.org/pipermail/python-list/2001-March/072078.html . I think the only reason slice objects need to be comparable is only to suppress inheritance of the default hash from object. This RFE is ripe to be rejected. Slice objects are really meant to be internal structures and not passed around in the user's code. You can always use tuples instead of slices and convert the to slices with slice(*t) when needed.
