Open question: For people who had upvoted #6579, what use cases still need addressing?

Checklist

My suggestion meets these guidelines:

• [?] This wouldn't be a breaking change in existing TypeScript/JavaScript code
• [?] This wouldn't change the runtime behavior of existing JavaScript code
• [?] This could be implemented without emitting different JS based on the types of the expressions
• [?] This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, etc.)
• [?] This feature would agree with the rest of TypeScript's Design Goals.

Beginne mit dem Lesen des Vorgänger-Issues #6579, der Änderungen in #40336 und des im Update vom 2023-04-11 verlinkten Dokuments. Überprüfe die verbleibenden Anwendungsfälle im Kommentar-Thread und erarbeite einen konkreten Vorschlag mit Beispielen; das Issue definiert weder einen Einstiegspunkt für die Implementierung noch ein klares Abschlusskriterium.
