It just occurred to me today, and I verified, that '+1' is also seen as
a string.
>>> '{0[-1]}'.format({'-1': 'neg int key'})
'neg int key'
>>> '{0[+1]}'.format({'+1': 'neg int key'})
'neg int key'
>>> '{0[+1]}'.format([1,2,3])
Traceback (most recent call last):
File "<pyshell#16>", line 1, in <module>
'{0[+1]}'.format([1,2,3])
TypeError: list indices must be integers, not str
