Conflict with Swoole's `defer()` function in Laravel

Description

I am currently using the Swoole 5.1.1 extension, which has implemented the defer() function since version 4.2.9. This function accepts a Closure as its first argument, leading to a conflict with Laravel's newly introduced defer() helper.

The current implementation of Laravel's defer() involves using two classes, which can be a bit cumbersome to call directly. It would be helpful to consider providing a more convenient alternative, such as a dedicated Facade or another abstraction, to avoid conflicts with Swoole's existing functionality and simplify usage.

Please note the following classes:

• Illuminate\Concurrency\ForkDriver
• Illuminate\Concurrency\ProcessDriver
• Illuminate\Concurrency\SyncDriver

These classes internally call the defer() function, which will cause conflicts when using the Swoole extension.

Steps To Reproduce

Enable the Swoole extension and attempt to use the defer() helper function

Thank you for the context.

I believe this issue extends beyond Octane and impacts both the main framework and Sail

I believe the defer function name is already registered with the Swoole extension, which could cause conflicts with existing projects that rely on Swoole’s defer function or have the Swoole extension enabled. Unfortunately, I think Laravel should consider renaming the defer function to avoid these conflicts.

There is a workaround by disabling functions in Swoole with:

swoole.use_shortname = off

However, considering Laravel's history of prioritizing a frictionless developer experience, I believe a better long-term solution may be found.
