NAME
       [Array::RefElem](https://www.chedong.com/phpMan.php/perldoc/Array%3A%3ARefElem/markdown) - Set up array elements as aliases

SYNOPSIS
        use [Array::RefElem](https://www.chedong.com/phpMan.php/perldoc/Array%3A%3ARefElem/markdown) qw(av_store av_push hv_store);

        av_store(@a, 1, $a);
        av_push(@a, $a);
        hv_store(%h, $key, $a);

DESCRIPTION
       This module gives direct access to some of the internal Perl routines
       that let you store things in arrays and hashes.  The following
       functions are available:

       av_store(@array, $index, $value)
           Stores $value in @array at the specified $index.  After executing
           this call, $array[$index] and $value denote the same thing.

       av_push(@array, $value)
           Pushes $value onto the @array.  After executing this call,
           $array[-1] and $value denote the same thing.

       hv_store(%hash, $key, $value);
           Stores $value in the %hash with the given $key. After executing
           this call, $hash{$key} and $value denote the same thing.
