Return values of some AbstractAdapter methods do not reflect the annotated return type

[ravcz]

Bug Report

There is wrong return type in

zend-cache/src/Storage/Adapter/AbstractAdapter.php

/**
 * Remove an item.
 *
 * @param  string $key
 * @return bool
 * @throws Exception\ExceptionInterface
 *
 * @triggers removeItem.pre(PreEvent)
 * @triggers removeItem.post(PostEvent)
 * @triggers removeItem.exception(ExceptionEvent)
 */
public function removeItem($key)

Expected behavior

There should be @return mixed

There is calling internally
return $this->triggerPost(FUNCTION, $args, $result);

which is returnng mixed.
