Really excited to see the discussion about this feature being brought up again, thanks for working on this :)
One thing I would suggest is to add a base interface `Attribute` and multiple sub-interfaces such as `ClassAttribute`, `MethodAttribute`, and `PropertyAttribute` just like hack lang ( https://docs.hhvm.com/search?term=HH%20Attribute ) This allows one to declare attributes that can only be used with classes ( e.g `ORM\Entity` ), so PHP and check against them at runtime and throws an error when an attribute is used in the wrong place. ```php namespace ORM { class Entity implements \ClassAttribute { ... } } namespace Foo { use ORM; <<ORM\Entity(...)>> // <-- Error function bar(): void {} } ``` I also question whether the following syntax would be supported: ```php <<ORM\Entity(...), ORM\Table(...)>> class Use {...} ``` I'm really looking forward to this since it can help bring more features into PHP such as : - https://docs.hhvm.com/hack/attributes/predefined-attributes#__entrypoint - https://docs.hhvm.com/hack/attributes/predefined-attributes#__memoize - https://docs.hhvm.com/hack/attributes/predefined-attributes#__sealed Regards. -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
