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.
Regards,
Alex
