I'm starting to see this error even for plain text strings in existing code:

>>> dunder_methods = '''

d[k]          d.__getitem__(k) -> value 
                   \--> d.__missing__(k) -> value
                    \-----------> raise KeyError(k)
d[k] = v      d.__setitem__(k, v) -> None
del d[k]      d.__delitem__(k) -> None

'''

SyntaxError: invalid escape sequence \-


These not easily suppressed messages are really annoying.  We don't have to inflict this on our users.  IMO, this is the least user friendly change to Python 3.8 and as far as I can tell, it is entirely unnecessary (we've lived without it for 28+ years).
