Illuminate/Support package does not declare Laravel/SerializeClosure as a Dependency

Description

I use some Illuminate packages without the Laravel/Framework package in a project and I've started getting errors for "Error: Class "Laravel\SerializableClosure\Support\ReflectionClosure" not found in file /path/to/project/vendor/illuminate/support/Onceable.php on line 66"

Checking the dependency list for the Support package in composer.json, I can't see "laravel/serializable-closure" package listed there which is causing the error when it's not listed elsewhere (i.e. in the main laravel/framework package where it is listed).

Steps To Reproduce

Install 'Illuminate/Support' by itself and use a function that calls the "Onceable" class.

Thanks for reporting this. I sent in a PR to add this to the package's suggest list: #52673

I get same error:
PHP Fatal error: Uncaught Error: Class "Laravel\SerializableClosure\Support\ReflectionClosure" not found in vendor/illuminate/support/Onceable.php:66
You can install laravel/serializable-closure package to fix this issue:
composer require laravel/serializable-closure

so you probably did not study this thread thoroughly. For clarification: PR #52673 did not fix this "automagically", it has just added laravel/serializable-closure to the suggested packages. So, if you are using illuminate/support independently (outside of a Laravel project), you still need add this:

$ composer require laravel/serializable-closure

tested in an ancient ZF1 project which uses once() helper with latest illuminate/support v11.43.2
