In the following code NetBeans wrongly flags `defaults` as an unused variable.

    export default (function(){
        const Module = function () {

            var defaults = {
                prop: 'value'
            };

            this.options = defaults;

            return this;
        };

    })();

The bug disappears when I change the first line to anything other than `export default` (e.g. `export const Module` or `return const Module`).

Other connected features also don't work, like renaming.

A workaround is to first define a variable and then export it:

    const Module = (function(){
        const Module = function () {

            var defaults = {
                prop: 'value'
            };

            this.options = defaults;

            return this;
        };

    })();

    export default Module;
