Re: [RFC] Arrow functions / short closures

Hi, To start with, I personally understand why a prefix character is needed before parenthesis to make the parser simpler. I would like another simpler option but will have to investigate more on this. My question would be: whatever syntax we are going to use that has arrow syntax, let's say *$f = \($x) => $x * 2;* are we going to also support the arrow block version?: *$f = \($x) => {* * // more operations that will have better visible on multi-line* * return $x * 2;* *}* This is present in other languages and was thinking that we could have it in PHP also.
