How does pandas.options autocomplete work in pylance?

[ilan-gold]

See https://stackoverflow.com/questions/77802222/how-does-pandas-options-auto-completion-work-vscode for my question, but it basically boils down to how the dynamically built pandas.options object can have autocomplete via pylance. I was under the impression static analyzers could not do this. Is this from closed-source additions or am I missing something? Are these additions (pyi files?) released with every pandas release?

I would like to implement something similar (dynamically built settings object), but am running into the issue that I can't get VSCode autocomplete.
