How To Install perl-Hash-StoredIterator on CentOS 7
Introduction

What is perl-Hash-StoredIterator
In perl all hashes have an internal iterator. This iterator is used by the each() function, as well as by keys() and values(). Because these all share use of the same iterator, they tend to interact badly with each other when nested. Hash iterator inside a hash. This allows you to store the current iterator, use each / keys / values etc., and then restore the iterator, which helps you to ensure you do not interact badly with other users of the iterator. Along with low-level get / set / init functions, there are also 2 variations of each() that let you act upon each key/value pair in a safer way than vanilla each(). This module can also export new implementations of keys() and values() that stash and restore the iterator so that they are safe to use within each().
