[8.x] Queued closure listeners

[taylorotwell]

It is currently impossible to define a Closure based event listener that should also be queued. This adds that functionality.

This is also the first addition of a namespaced function to Laravel.

use function Illuminate\Events\queueable;

Event::listen(queueable(function (Something $event) {
    //
});

In addition, catch, onConnection, onQueue, and delay methods are available:

Event::listen(queueable(function (Something $event) {
    //
})->catch(function (Something $event, $exception) {
    //
})->onConnection(null)->onQueue(null)->delay(now()->addSeconds(10)));

This may also be used with model event listeners:

App\User::created(queueable(function ($user) {
    info($user->name);
}));

This can side effect?

Can be like?;

if (! function_exists('queueable')) {
// method here
}

It's namespaced.

You still need the if method exists, actually. The function can still conflict with a global install of itself.
