Feature or enhancement

While reading new ruff release notes: https://astral.sh/blog/ruff-v0.4.0 I found that it has a new nice parser feature that we can addopt. Before:

>>> from x import
  File "<stdin>", line 1
    from x import
                 ^
SyntaxError: invalid syntax
>>> from . import
  File "<stdin>", line 1
    from . import
                 ^
SyntaxError: invalid syntax

>>> from x import
  File "<stdin>", line 1
    from x import
                 ^
SyntaxError: Expected one or more names after 'import'
>>> from . import
  File "<stdin>", line 1
    from . import
                 ^
SyntaxError: Expected one or more names after 'import'
>>> 

I have a PR ready :)

Why ignoring just import?

>>> import
  File "<stdin>", line 1
    import
          ^
SyntaxError: invalid syntax

I will update my PR.
