Invalid error messages after GH-134077 #135422
Description
Bug report
In #134036 (PR: #134077) I broke this use-case:
# ex.py
raise AssertionError() from None
print(1,,2)Running ./python.exe ex.py on it produces:
» ./python.exe ex.py
File "/Users/sobolev/Desktop/cpython/ex.py", line 1
raise AssertionError() from None
^^^^
SyntaxError: did you forget an expression after 'from'?
Which is not correct. I am fixing it right now, sorry! :(
