Transform iife into iiafe

[frzi]

What are the thoughts of transforming iife to iiafe? (immediately invoked arrow function expressions)?

Input Code

(function () {
   /* ... */
})();

// or

(function () {
   /* ... */
}());

Transformed Code

(_=>{/*...*/})()

[j-f1]

What about just a block?

{/*...*/}

Transforming iifes into a simple block would work for iife at top level, without any arguments.

But a little trickier otherwise, I think(?).

let dynamicClass = (function ($) {
    function MyClass() {}
    MyClass.$ = $
    return MyClass
})(jQuery)

which now transform to:

let dynamicClass=function(a){function b(){}return b.$=a,b}(jQuery);

With an iiafe:

let dynamicClass=(a=>{function b(){}return b.$=a,b})(jQuery);

This has already been brought up. There is an issue for that already - #428 . Closing this and tracking it there.
