Well, the Ruby/Rust syntax would serve us well here too:
$things->forEach(|$v| { foo($v); bar($v); }); On 19 Jun, 2017, at 09:43 PM, Rasmus Schultz <ras...@mindplay.dk> wrote: I actually like this syntax, but what would it look like for multi-statement closures? A nested set of curly braces around the body would look pretty messy. $things->forEach({$v => { foo($v); bar($v); }}); On Mon, Jun 19, 2017 at 4:43 PM, Levi Morrison <le...@php.net> wrote: On Sun, Jun 18, 2017 at 1:44 PM, Ilija Tovilo <ilija.tov...@me.com> wrote:
Sorry, I wasn’t aware of that. What do you think of the Ruby/Rust style syntax that Levi proposed a while back? $someDict ->map(|$v| $v * 2) ->filter(|$v| $v % 3); This one has a few advantages: 1. It has syntax (a lot of) developers are already familiar with 2. It has no ambiguities and is fully backward compatible 3. It’s the shortest of all options available (two `|` characters and one space)
We determined that the arrow between the parameters and the expression would still be required. Given this limitation I think this syntax is seviceable: $someDict ->map({$v => $v * 2}) ->filter({$v => $v % 3}); Sometime this week I intend to start another thread that narrows us down to two choices.
