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 parentheses is required.
2. I don't remember. haha Em qua, 13 de mar de 2019 às 12:57, Nikita Popov <nikita....@gmail.com> escreveu: > 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 This is based on a previous (withdrawn) proposal by Levi & Bob.
