#5725: [with patch; needs review] sequences -- bring coverage to 100%; don't
allow
hashing of mutable sequences

--------------------+-------------------------------------------------------
Bring up the coverage of sequence.py from 59% to 100%. Also, sequences
allowed hashing even when they are mutable which *breaks* all the Python
algorithms that rely on hashing! This was because I didn't understand
this fast about Python when I implemented Sequences.
If there is any fallout as a result of eliminating hashing, then that
other code must be fixed, because it would surely exhibit subtle bugs.
