Hi internals, https://wiki.php.net/rfc/trailing_comma_in_parameter_list mentioned

So I'm wondering if anyone's interested in revisiting this: - It'd be easy to forget that function parameters support trailing commas, but not closure uses, especially if you're new to the language. - Supporting trailing commas in multi-line declarations would make version control history easier - if you had a closure for which `fn` wouldn't work (a list of values *and references* to use, or a list of statements), it'd be convenient to split it up across multiple lines e.g. ``` $incrementing_id = 0; return \array_map(static function (array $map) use ( $function, $some_data_structure, $some_flag, &$incrementing_id, ): ReturnType { ``` -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: https://www.php.net/unsub.php
