Suggest a future feature name in from __future__ import #145868
Description
Feature or enhancement
Proposal:
When from __future__ import with a wrong name, maybe it is a typo. We can suggest a possible name. Just like:
>>> from __future__ import annotation
File "<python-input-0>", line 1
from __future__ import annotation
^^^^^^^^^^
SyntaxError: future feature 'annotation' is not defined. Did you mean: 'annotations'?One possible way is just read the line and analyse.
Has this already been discussed elsewhere?
This is a minor feature, which does not need previous discussion elsewhere

The error is raised at the interpreter's level. However we need to use
_Py_CalculateSuggestionsin this case. Currently, the only future that is not a nop isannotationsso I wonder whether it will really be useful (and we also want to move away from it and only new versions will see the improved message).pythongh-145868: Suggest names on typos in `__future__` imports
