New submission from Antoine Pitrou <pit...@free.fr>:
This doesn't happen on 2.x cPickle, where PUT keys are simply treated as
strings.
>>> import pickle, pickletools
>>> s = b'Va\np-1\n.'
>>> pickletools.dis(s)
0: V UNICODE 'a'
3: p PUT -1
7: . STOP
highest protocol among opcodes = 0
>>> pickle.loads(s)
