= (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);
|

|

*
|
||
* If you want to put your handler before non-indexed handlers, specify a negative value.
