export * from './core/v4';
//import createStorageHook from './core/v4';
//export default createStorageHook

//console.log(exports.default)

import createStorageHook from './src/core';

Expected behavior:

know "src/core" has default import

Actual behavior:

Error:(2, 8) TS1192: Module '"src/core"' has no default export.

export * doesn't include default exports

[DanielRosenwasser]

That should be what this issue is - that the error message is bad. We should detect the export * and hint that an export * doesn't create a default export.
