[issue19080] Enrich SyntaxError with additional information

[Terry J. Reedy]

Terry J. Reedy added the comment:

Currently,
>>> * 2 # or * a
SyntaxError: can use starred expression only as assignment target
This conflicts with your desired message. It cannot change because *a, at least, is a valid statement prefix in a way that '/ a' is not.

Most other things give an uninformative generic 'invalid syntax' message (plus a more informative location indicator). If you can find a way to improve this, lots of people would be happy ;-).
