Re: [RFC][Discuss] Arrow Functions

Hi Levi, Levi Morrison wrote:

Here is an example of an existing closure:

    function ($x) use ($arr) {
        return $arr[$x];
    }

This RFC proposes syntax and semantics to simplify this common usage to:

    fn($x) => $arr[$x]

Is it necessary to introduce a new keyword, fn? I think you'd get a similar benefit from:

    function($x) => $arr[$x]

Likewise, is it necessary to restrict auto-capture to the => syntax? Couldn't we allow the following?

    function ($x) {
        return $arr[$x];
    }

That being said, I broadly support your goals. -- Andrea Faulds https://ajf.me/
