Some "global" variables need to be renamed, so they don't clash in the final bundle `jquery-ui.js` (because, each file UMD wrapper gets removed for optimization).

Shall we rename them case-by-case like the above, or shall we be more programmatic and follow some kinda pattern through all the files that prevents them from clashing? Eg. by using key-value pairs objects:

```javascript
var core = {
  uuid: 0,
  ...
};
```
