Notation for generics to PHP: `#<>`

Disclaimer: I assume someone has already suggested this and there are good reasons it hasn't happened!

Inspired by a conversation with @pronskiy after my talk "PHP Generics Today (Almost)" at IPC Munich

Examples:

class Queue #

Run composer install and then vendor/bin/phpunit. Make sure basic test works.

Write a function that converts an integer into a roman numeral.

Create a new directory and cd into it:

	I want this project to support PHP 8.3, 8.4, and 8.5 with a CI matrix. Right
	now it probably only supports one version. Here's the plan:

	## Goals
	- Support PHP 8.3, 8.4, and 8.5
	- Local Docker services for each version
	- GitHub Actions matrix that runs CI against all three
	- Infection (mutation testing) runs only on 8.5 in a dedicated job
	- Single `composer.lock` that works on all three versions (project, not
	library — locked dependencies only)

	// Example of the #[Friend] attribute available from https://github.com/DaveLiddament/php-language-extensions

	class Person {

	#[Friend(PersonBuilder::class)]
	public function __construct() {}
	}

	class PersonBuilder {
	public function build(): Person {
