Re^4: Subarray in a hash: Can't use string ("STRING") as a HASH ref while "strict refs" in use

No, ( ) is used for lists. Lists are converted into arrays by assignment. Also, lists are converted into hashes by assignment.

Example: note the addition of the `undef` to make the hash work properly.

#!/usr/bin/env perl

use strict;
use warnings;
use feature   qw( :all );

# --------------------------------------
# Modules

use Data::Dumper;

# Make Data::Dumper pretty
$Data::Dumper::Sortkeys = 1;
$Data::Dumper::Indent   = 1;

# Set maximum depth for Data::Dumper, zero means unlimited
local $Data::Dumper::Maxdepth = 0;

# --------------------------------------

my @a = my %h = ( 1, 2, 3 );

say Dumper \@a;
say Dumper \%h;
