Some examples:\n\n* [`Enum._add_alias_`](https://docs.python.org/3/library/enum.html#enum.Enum._add_alias_)\n* [`Enum._add_value_alias_`](https://docs.python.org/3/library/enum.html#enum.Enum._add_value_alias_)\n\n\n```python\n$ ./python\nPython 3.15.0a0 (heads/main:e18dda96c9, Sep 28 2025, 18:14:51) [GCC 13.3.0] on linux\nType \"help\", \"copyright\", \"credits\" or \"license\" for more information.\nCtrl click to launch VS Code Native REPL\n\u003e\u003e\u003e from enum import Enum\n\u003e\u003e\u003e Enum._\nEnum._add_member_(                  Enum._convert_(     Enum._find_data_repr_(     Enum._find_new_(\nEnum._check_for_existing_members_(  Enum._create_(      Enum._find_data_type_(     Enum._get_mixins_(\n\u003e\u003e\u003e Enum._add_alias_\n\u003cfunction Enum._add_alias_ at 0x7d38f05fc1d0\u003e\n```\n\nI don't know if this also affects other modules... but I guess it would be great to have a test that checks the completion coverage of the REPL across the stdlib - or is there already a test like this?\n\nEither way, I'm happy to help fix this issue and create a PR if one could guide me to the place where the REPL builds the \"completion database\" 🙂 \n\n### CPython versions tested on:\n\nCPython main branch\n\n### Operating systems tested on:\n\nLinux\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-139418\n* gh-139985\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/RafaelWO","@type":"Person","name":"RafaelWO"},"datePublished":"2025-09-28T16:33:21.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":5},"url":"https://github.com/139398/cpython/issues/139398"}
