Follow-up to this tweet — trying to figure out how to get auto-imports to work for subpackages (my-lib/subpackage) ideally without resorting to declare module, and without forcing consumers of the library to adopt a specific TypeScript configuration.
If you open this repo in VSCode, it should be possible to auto-import add from my-lib and multiply from my-lib/subpackage inside index.js, but only the first of those works.
