[php-src] Issue #8421: Attributes that target functions are not valid for anonymous functions defined within a method

Issue: https://github.com/php/php-src/issues/8421 Comment Author: kallesommernielsen A closure is not a procedural function, a closure is actually a object of the \Closure class with the method body being the code executed inside the __invoke() magic method for which the closure syntax is sugar for really. I doubt closures will be supported by attributes anytime soon as it will require copying attributes to the object and you would then only be able to fetch it via ReflectionObject as there isn't really another reliable way to accomplish this.
