Use variadic functions when authorizing actions with additional context

[ethanransdellverse]

Laravel is often flexible when calling methods by allowing arrays or an undefined number of variables. This is even present in Auth middleware.

I thought we could support that pattern when supplying additional context for an authorization check:

• https://laravel.com/docs/11.x/authorization#supplying-additional-context
• https://github.com/laravel/framework/blob/b030dbb3c77aa553b976a8fae4ce823c3459e702/src/Illuminate/Contracts/Auth/Access/Authorizable.php

The innerworkings of can($abilities, ...$arguments) wouldn't need to change, as $arguments would automatically come through as an array, but unfortunately it would be a breaking change for anyone that implements the Authorizable interface.

Example:

interface Authorizable
{
  public function can($abilities, ...$arguments);
}
