How do I extend another VueJS component in a single-file component? (ES6 vue-loader) : <p>I am using vue-loader (<a href="http://vuejs.github.io/vue-loader/start/spec.html" rel="noreferrer">http://vuejs.github.io/vue-loader/start/spec.html</a>) to construct my <code>*.vue</code> single-file components, but I am having trouble with the process from extending a single-file component from another.</p>

<p>If one component follows the spec to <code>export default { [component "Foo" definition] }</code>, I would think it is just a matter of importing this component (as I would with any child component) and then <code>export default Foo.extend({ [extended component definition] })</code></p>

<p>Unfortunately this does not work. Can anyone please offer advice?</p>
