**
= (function) returned function accepts a single numeric parameter that represents z-index of the handler. It is an optional feature and only used when you need to ensure that some subset of handlers will be invoked in a given order, despite of the order of assignment.
> Example:
| eve.on("mouse", eatIt)(2);
| eve.on("mouse", scream);
| eve.on("mouse", catchIt)(1);
* This will ensure that `catchIt()` function will be called before `eatIt()`.
*
* If you want to put your handler before non-indexed handlers, specify a negative value.
* Note: I assume most of the time you don’t need to worry about z-index, but it’s nice to have this feature “just in case”.
