I have two doubts about the RFC:
1. Your example with "($x) => $x" consider the use of "$x => $x", but not
specifically "($x) => $x". I mean: maybe it can accept "($x) => $x" but not
"$x => $x" because of the array conflict (as mentioned), and with that we
avoid to create a new keyword "fn". So

There is another possible reason to put the expression last: It
preserves the ordering of the intended foreach loop. What I mean to say

I use this format a lot in javascript, so I like not having any indicator.
I can't remember which language it was, but they didn't even require the

Arrow functions are ternary operators to functions.
While they are nice and shorten, they can be hard to read at times;
considerably to people who aren't used to them which is surprisedly a
majority of PHP programmers.
Having them optional sure, but not necessary.

Hi internals,
Motivated by the recent list comprehensions RFC, I think it's time we took
another look at short closures:
https://wiki.php.net/rfc/arrow_functions_v2
This is based on a previous (withdrawn) proposal by Levi & Bob. It uses the
syntax
fn($x) => $x * $multiplier
and implicit
There were specific reasons for it tho I can't recall all the details
off the top of my head. Part of it related to the underlying structures
of attributes and namespace nodes not being the same and cannot be user
interchangeable in the code, unless only inspected at the nodeptr level.
