Can anyone summarize why these did not move forward? Nikita's proposal sounds pretty good IMO, and I think the follow up proposal would have been nice, too.

Also IDEs exist and can tell you the name of the argument. I would assert a counter to your assertion that this feature would not be *that* useful, at least several known use-cases. The known use-cases include: 1. Querying, be it SQL or some other query language. 2. Wrapping API calls (which is a form of querying.) 3. Instantiating properties of an object via __construct(). I assume most on this list are not fans of WordPress but that notwithstanding WP_Query() is a good example of a class that accepts an array of arguments on instantiation: - https://developer.wordpress.org/reference/classes/wp_query/ Unfortunately PHP can't type check those WP_Query() arguments, but it could type check named parameters of a query() method. Yes, you can model all arguments as properties of an object, but then how would you instantiate that class? Named properties would make doing so much less tedious and allow it to be done in a single expression rather than requiring multiple assignment statements. -Mike P.S. This would be on my top 5 list of features I would like to see added in PHP 8. FWIW. -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
