declare(strict_types=1) causes static code check failure

[lenaorobei]

The old version of PHP Codesniffer, as well as old sniffs, are used for a static code check.

As a result, when adding declare(strict_types=1); causes sniffer to throw a warning on the PSR-2 standard.

As a workaround in #69 I had to add @codingStandardsIgnoreFile annotation. The old version of PHP Codesniffer has made also impossible to use @codingStandardsIgnoreStart and @codingStandardsIgnoreEnd at the beginning of the file.

Suggest updating "squizlabs/php_codesniffer": "1.5.3" to "squizlabs/php_codesniffer": "3.0.1" and use updated sniffs for Magento 2.

In addition, return type : array leads to Short array syntax must be used; expected "[]" but found "array()" error.
