Example
```
const isEditorWithUI = <T extends Editor>(value: T): value is T & EditorWithUI => {
  // first see, if required keys are available
  if (isRaw<EditorWithUI>(value, "ui")) {
    // then check these keys if they pass the type-guard
    return typeof value.ui === "object";
  }
  return false;
};
```
