[RFC] Short Array Variable Shorthand

Hi folks! Today, I want to announce my second RFC to php 8.7 https://wiki.php.net/rfc/array_shorthand This RFC brings a IMO useful syntactic sugar to array's construction and destruction. I hope you'all find this interesting! To be short: ``` $point = [:$x, :$y, :$z]; // ['x' -> $x, 'y' -> $y, 'z' -> $z] [:$x, :$y, :$z] = $point; // reverse. ``` We also support the foreach syntax ofc, see examples in the RFC. Same feature has been implemented in perl. And 13 years ago the named argument RFC have already list this as part of the future scope [1] Some may ask why don't you propose this for all functions but just for the [] syntax in arrays? Well, sadly I don't have enough time and energy to put in php now (I am unfunded) so I will leave it for others if they want in the future. Again I hope you'all find this useful and interesting :) Thank you, Weilin Du [1]: https://wiki.php.net/rfc/named_params#shorthand_syntax_for_matching_parameter_and_variable_name
