Does that only work with something like babel? Because using the node 5.1 repl (and chrome console) you get:<p><pre><code>    &gt; let func = () =&gt; {}
    undefined
    &gt; func.name
    &#x27;&#x27;
    &gt; function longfunc() {}
    undefined
    &gt; longfunc.name
    &#x27;longfunc&#x27;</code></pre>
