Public bug reported:
I accidentally came across this annoying 'feature' or more likely, bug.
The following code
f"...foo ... {**kwargs} ..."
produces a very basic syntax error message with no line number in the source
file:
File "<fstring>", line 1
(**kwargs)
^
SyntaxError: invalid syntax
This is the error message I would expect from the interpreter, but not when
running a python script. A demo script is as follows:
''' f-string bug demonstration '''
def main(*args, **kwargs):
print(f"main() called with *args={*args}, **kwargs={**kwargs}")
With a longer python file, it is hard to find the offending line.
Should the line number be displayed in the error message?
