Argument description attribute would be nice

Description

I am now in a situation where I would want argument description available in reflection.
One way to do that would be an argument description attribute.
Something like

function processOrder(
    #[ArgumentDescription("The unique identifier for the order.", example: "ORD12345")]
    string $orderId,
    #[ArgumentDescription("The total amount for the order in USD.", example: 99.99)]
    float $amount
) {
(...)
}

Would be nice.
Definitely don't have leftover time/energy to pursue an RFC tho.

Hi @divinity76. Can you clarify why we need native support for this attribute? You could just create your own. https://3v4l.org/s368H

@iluuu1994 Neat! I didn't know you could do that

That would indeed suffice. There's also docblock-comment-parsers like https://github.com/jasny/phpdoc-parser

Closing.

@devnexen feel free to re-open or make a new one if you think it has sufficient merit to gain native upstream support. (I'd be positive fwiw)

To be honest, I did not have any opinion really on it just wanted to have relevant people having a look into it :)
