[issue44447] Syntax Error not as detailed as shown

New submission from Eesa Ibrahim Khokhar <khokhareesa.home@gmail.com>:

I was testing the new features for python 3.10 beta 3, and noticed the errors were not as detailed as shown in the docs.

I have an image below:

In the docs, it was said that the entire generator statement would be pointed out by carets. However, it only pointed out 'for', and the error was not as detailed as shown in the docs.

Andre Roberge <andre.roberge@gmail.com> added the comment:

Your example is different than the one in the documentation (What's new).

>>> (x, x for x in range(7)) # Your example
File "<stdin>", line 1
(x, x for x in range(7))
^^^
SyntaxError: invalid syntax

>>> foo(x, x for x in range(7)) # Example similar to the docs
File "<stdin>", line 1
foo(x, x for x in range(7))
^^^^^^^^^^^^^^^^^^^
SyntaxError: Generator expression must be parenthesized

>>> [x, x for x in range(7)] # Yet a different example
File "<stdin>", line 1
[x, x for x in range(7)]
^^^^
SyntaxError: did you forget parentheses around the comprehension target?

Indeed, as Andre mentions your example is different because in you case the call is interpreted as a generator comprehension, not as a function call.
