Missing list of incomplete features
Documentation
Within the CLI we have the command line switch --enable-incomplete-feature which expects a feature name to enable.
Until now I have not been able to find a list of possible (incomplete/under development) features, which I could enable over here.
Have I missed something?
It's defined here, but you're right that it's not documented anywhere:
https://github.com/python/mypy/blob/83660d0ad72ab5a61cea5fe5955e66c33ef54111/mypy/options.py#L70-L73
So, we have to go through the codebase to identify all of the features that can be enabled with the --enable-incomplete-feature switch if I am not wrong?
I also noticed that the enable_incomplete_feature settings key is not documented. But if I add enable_incomplete_feature = ["Unpack"] to my pyproject.toml, it seems to work as expected.
I think this is somewhat intentional; incomplete features are experimental and incomplete and may be broken in some way, so we don't want to advertise them too much.
However, it should be fine to add a list to the documentation with a note that these features are experimental, we don't guarantee any form of backward compatibility, use at your own risk, etc.

I think the latter is a great idea. I'll add a TODO to look into this when I find the time otherwise feel free to pick up this issue and resolve it.
