Default import returns an object instead of function

[Vladimir]

Using vanilla Node withour preprocessors, importing givens returns an object with property default, but type says it's a function:

https://stackblitz.com/edit/node-j89pac?file=index.js

// run `node index.js` in the terminal

import givens from 'givens'

console.log(givens) // { default: fn } instead of givens

This is because you transpile it to exports.default = fn instead of module.exports = fn, I think
