Squiz.Commenting.FunctionComment false positive when function contains closure

[josephzidell]

There is a false positive in src\Standards\Squiz\Sniffs\Commenting\FunctionCommentSniff.php

This code throws error: Function return type is not void, but function is returning void here

/**
 * Test function
 *
 * @return array
 */
public function test()
{
	function () {
		return;
	};

	return [];
}

The same issue we have also in case:

function test()
{
    new class() {
        public function test() {
            return;
        }
    };

    return [];
}

@josephzidell Here is my PR with fix for both cases: #1551

Thanks for coming up with a fix so quickly

@webimpress Found another, related issue

Code:

/**
 * Test function
 *
 * @return void
 */
public function test()
{
	function () {
		return 4;
	};
}

Error: Function return type is void, but function contains return statement

@josephzidell I've added more tests 4a28555
and all of them pass:
https://travis-ci.org/squizlabs/PHP_CodeSniffer/builds/252693542?utm_source=github_status&utm_medium=notification

It seems that my previous solution also covers these cases.
