Can a Sequence be infinite? If so, an equality test of two nonterminating sequences would be a nonterminating operation.
Do Sized and Reversible imply that a sequence terminates? Could __len__ return inf?
Perhaps Ordered is a requisite condition for defining a comparator for
Sequences.
OrderedSequence?
Are there unordered Sequences for which a default __eq__ /
__cmp__ (et.
al) would be wrong or inappropriate?

This one raises the question of where you put the single-item accessors. And sliced __delitem__ may be difficult to implement efficiently without knowing the internals of the sequence type.
