default export handling in CJS and IIFE bundles #587

export default function () {}

var doStuff = (function () {
    'use strict';
    function index () {}
    return index;
}());

'use strict';
function index () {}
module.exports = index;

export default function () {}
export function other() {}

'use strict';

function index () {}
function other() {}

exports['default'] = index; // Boom, broken
exports.other = other;

(function (exports) {
    'use strict';

    function index () {}
    function other() {}

    exports['default'] = index; // Boom, broken
    exports.other = other;

}((this.doStuff = this.doStuff || {}))); // Also, why this check only here? In some cases the behavior changes completely.

window.doStuff()

window.doStuff['default']()
