Hi internals,
I've created a new RFC
https://wiki.php.net/rfc/trailing_comma_in_closure_use_list to allow a trailing
comma in closure use lists. This is already supported for argument and
parameter lists.
```
$longArgs_longVars = function (
$longArgument,
$longerArgument,
$muchLongerArgument, // Trailing commas were allowed in parameter lists in
PHP 8.0
) use (
$longVar1,
$longerVar2,
$muchLongerVar3 // The RFC proposes allowing a trailing comma here.
) {
// body
};
```
Earlier discussion can be found on https://externals.io/message/110715
(Permitting trailing commas in closure use() declarations)
> I think if there are no objections on list, we can just land this change.
> Given how positive the outcome of the "trailing comma in parameter lists"
> RFC was this doesn't seem controversial.
This may potentially be more controversial than "trailing comma in parameter
lists"
(an earlier vote was 16-22 for closure use vs 24-20 for parameters in
https://wiki.php.net/rfc/list-syntax-trailing-commas).
It's worth considering just merging if there are no objections before voting on
the RFC starts
(planned 14 days from now, on July 15th)
Thanks,
- Tyson
