pyrepl autocomplete from x import <tab> to only display public members

Feature or enhancement

Proposal:

When using autocomplete in the REPL, from x import <tab> will show all non-underscore prefixed members. This is a dir-like behavior that is useful to inspect and understand what can be imported.

However, this mechanism isn't filtering on __all__ of the module and can yield a long list of non-useful candidates to autocomplete. Two examples shown below, pathlib and collections.abc.

The feature request is that when a user enters from x import <tab> only the candidates defined in __all__ are listed.

Has this already been discussed elsewhere?

從 from x import <tab> 的 pyrepl 自動完成入口開始，檢查現有的類 dir 候選項篩選邏輯。檢查自動完成測試（如果有），並使用 issue 中的 pathlib 和 collections.abc 範例來驗證只有由 __all__ 公開的名稱才會被列出；連結的 PR gh-156146 表明相關工作已經在進行中。
