Cross-interpreter support for efficient sharing of frozendicts

Feature or enhancement

Proposal:

The concurrent.interpreters module for subinterpreters handles sharing/sending values across interpreters with direct sharing of some basic immutable types, and a fallback to pickling others. As an immutable container, tuples are supported (as long as all items are themselves shareable). Similarly, I think it would be good to support sharing frozendict without serialization (if keys & values are shareable).

Because dictionaries are so fundamental and common, having a better and more performant way to share such a mapping would significantly improve the experience of using concurrent.interpreters and InterpreterPoolExecutor.

Has this already been discussed elsewhere?

まず、オブジェクトの共有に関する concurrent.interpreters のドキュメントと、モジュールにおける共有可能なタプルおよびマッピングの既存の扱いを読んでください。すべてのキーと値が共有可能である場合に frozendict の共有がどのように機能するかを判断してください。完了の条件は、サポートされる値が pickling なしでインタープリター間を移動し、その動作が関連するテストでカバーされていることです。
