[v.6.2.2] export statement in es5.js

[puneetar]

Hi, I am seeing the following error when using es5.js

import { Option } from "funfix-core/dist/es5";

/node_modules/funfix-core/dist/es5.js:1092
export { isValueObject, is, equals, hashCode, hashCodeOfString, id, applyMixins, CompositeError, DummyError, NoSuchElementError, IllegalInheritanceError, IllegalStateError, IllegalArgumentError, NotImplementedError, TimeoutError, Either, Left, Right, Option, Some, None, Try, Success, Failure };
^^^^^^

SyntaxError: Unexpected token export

I wonder if there is something wrong with building es5.js
