minor changes

[isaeken]

This pull request includes minor changes to improve code clarity and functionality in the src/Illuminate/Auth/Access/Gate.php and src/Illuminate/Foundation/Http/FormRequest.php files.

Code clarity and functionality improvements:

• src/Illuminate/Auth/Access/Gate.php: Added a return null statement at the end of the callBeforeCallbacks method to explicitly return null if no result is found.
• src/Illuminate/Foundation/Http/FormRequest.php: Added a docblock comment to type-hint the $exception variable as \Illuminate\Validation\ValidationException in the failedValidation method.

How is $exception is not a string?

The return type of Illuminate\Validation\Validator@getException() is class-string<\Illuminate\Validation\ValidationException>, so $exception is a string.

framework/src/Illuminate/Validation/Validator.php

Lines 1535 to 1543 in 61492a8

	/**
	* Get the exception to throw upon failed validation.
	*
	* @return class-string<\Illuminate\Validation\ValidationException>
	*/
	public function getException()
	{
	return $this->exception;
	}

Furthermore, I don't think the new operator can be used with anything other than a class name, or that evaluates to a string representing a class name.

EDIT: clarification about new operator usage.

Although I also prefer that all null returns would be explicit, there are too many places in Laravel that rely on null to be implicitly returned.

I'd really like to see this particular change merged, and maybe done for all other places to make everything more explicit, but I wouldn't hold high hopes on that one.

I am closing this pull request because it lacks sufficient explanation, tests, or both. It is difficult for us to merge pull requests without these things because the change may introduce breaking changes to the framework.

Feel free to re-submit your change with a thorough explanation of the feature and tests - integration tests are preferred over unit tests. Please include it's benefit to end users; the reasons it does not break any existing features; how it makes building web applications easier, etc.

Thanks!
