I just tried to replace

```auto
		label: function() {
			return this.name;
		},

```

with

```auto
label: () => this.name,

```

and it didn't work. Is this expected? Obviously not important, just wondering if I am doing something silly

That is expected to not work. You should not use arrow functions in a node definition.

Unlike regular functions, arrow functions don't get their own `this`. Which means the function would have no way of addressing the node instance it is being called for.
