Old code using inline methods

Nobody has claimed this yet.

Inline methods in code like

```js
createLabels(keys, values, tooltips = {}) {
return arr.zip(keys, values).map(([name, value]) => {
return {
type: "label",
value: name,
onMouseDown: () => { this.update(name, value); }
};
});
}
```

are not supported and will break serialization and synchronization. For instance specific behavior please consider using connect from a parent object that has a class or use object behavior defined via the object editor.

Code that still relies on that (style halos etc.) will be removed.

Start by searching the repository for inline methods and code that relies on them, including style halos. Review the serialization and synchronization behavior described in the issue, then identify the remaining uses to remove or migrate; done means no unsupported inline-method usage remains.
