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.
