You've been given a solution by haukex in Re: 5.24 -> 5.28 -- what has changed in autovivification?.

Do you need more details? Here's an example:

#! /usr/bin/perl use warnings; use strict; use feature qw{ say }; use Data::Diver qw{ Dive }; use Data::Dumper; my $h1 = {}; my $h2 = {a => {b => {c => 42}}}; for my $h ($h1, $h2) { say "Found $h->{a}{b}{c}" if Dive($h, qw( a b c )); } print Dumper $h1, $h2;
Output:
Found 42 $VAR1 = {}; $VAR2 = { 'a' => { 'b' => { 'c' => 42 } } };

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]
