Per M Knutsen,

When accessing elements in hashes of arrays, arrays of hashes and other 
complex data-structures you should pay careful attention top the syntax 
you are using. The following example illustrates how you can retrieve 
and loop over an array of a hash:
#!/usr/bin/perl
use strict;
use warnings;
# Create array
my @names = ["Rick","Ray","Charles"];
# Create hash
my %myHash = ( "names" => @names );
foreach my $name ( @{$myHash{"names"} } ) {
    print $name."\n";
}
