Note that my advice is to use
$hash3{"@key"}

Whnever you use a composite key, you have the possibility of a collision.

use strict;

use Data::Dumper;
my %hash1 = ();
my %hash2 = ();
my @key1 = ( 'a b', 'c' );
my @key2 = ( 'a', 'b c' );
$hash1{"@key1"} = 'some value';
$hash1{"@key2"} = 'some other value';
$hash2{$key1[0]}{$key1[1]} = 'some value';
$hash2{$key2[0]}{$key2[1]} = 'some other value';
print "\%hash1 = ", Dumper \%hash1;
print "\%hash2 = ", Dumper \%hash2;
