gh-140382: Add support for `__getattr__` method to Argument Clinic by StanFromIreland · Pull Request #140376 · python/cpython

Wouldn't it make more sense to just support arbitrary dunder methods?

I think it's ok to add support of specific dunders on-demand. It's not too helpful in general, because sometimes we can do too much with slots, even override the docstring.

But please think about more generic case. For example, for most dunders we have very specific function signatures. It will be redundant and error-prone to specify this stuff by hand.
