A small nit: SortedSequence and SortedDicts should be mappings,
guaranteeing "fast" (preferably O(1)) access for any key (integral and
arbitrary, respectively). Therefore, in the case of a SortedDict the
user should be no more surprised at a complaint about hashability than
they should be in the case of a dict (especially considering the name!)
I'll grant that some users might be perfectly happy with O(log N)
"reasonably fast" access, but others would not be pleased.
