in reply to help with references
$h{2} isn't a reference to $h{1}. $h{2} is a reference to the same array that $h{1} refers to.
I think you probably want:
for my $i ( 1 .. 2 ) { my @new = @a; # copy of @a $h{"$i"} = \@new; # reference the copy }
Or (more concise way of saying the same thing)...
for my $i ( 1 .. 2 ) { $h{"$i"} = [@a]; }
package Cow { use Moo; has name => (is => 'lazy', default => sub { 'Mooington' }) } say Cow->new->name
