Problem

I would like to import a default export of a lib.
Unfortunately with tsx I couldn't do this:

import zennv from 'zennv';

export const env = zennv({...})

I got this error:
Error: _zennv.default is not a function

Expected behavior

Working with default imports.

zod or the extra index file doesn't seem necessary for the reproduction. Please keep it minimal as isolating the bug creates more work to vet your reproduction.

Yes it does, as it is needed for the param of the constructor.
