in reply to Loop through array of hashes

Why not use a function for that? 

use strict;
use warnings;

my %foo = ( one => 1, two => 2 );
my %bar = ( three => 3, four => 4 );
my %baz = ( five => 5, six => 6 );

dump_keys( $_ ) for \%foo, \%bar, \%baz;

sub dump_keys { print "$_\n" for keys %{+shift} }

Update: I am using ONE list without the need to wrap it in an array.

    It's that classic blunder, less well known than getting involved in a land war in Asia: use of numbered variables instead of an array! Especially when the OP calls for it.

    use strict;
use warnings;

my @aoh;
push @aoh, { one => 1, two => 2 };
push @aoh, { three => 3, four => 4 };
push @aoh, { five => 5, six => 6 };

dump_keys( $_ ) for @aoh;

sub dump_keys { print "$_\n" for keys %{+shift} }

    Update: jeffa has since revised his answer to make my comment irrelevant.

      Why don't you harass the other responses with your pedantry? Everyone in this post used numbered variables because the context was something else --- taking a reference. Please, learn how to read.
