Expected Behaviour

Input

export * from '@redux-saga/core'
import createSagaMiddleware from '@redux-saga/core'
export default createSagaMiddleware

Expected output

Output with createSagaMiddleware__namespace declared.

Actual Behaviour

Output

'use strict';

Object.defineProperty(exports, '__esModule', { value: true });

var createSagaMiddleware = require('@redux-saga/core');



Object.defineProperty(exports, "default", {
	enumerable: true,
	get: function () { return createSagaMiddleware__namespace.default; } 
});
Object.keys(createSagaMiddleware).forEach(function (k) {
	if (k !== 'default' && !Object.prototype.hasOwnProperty.call(exports, k)) Object.defineProperty(exports, k, {
		enumerable: true,
		get: function () { return createSagaMiddleware[k]; }
	});
});

Notice the reference to createSagaMiddleware__namespace which was not created.
