A simple solution is two concatenate the two keys into one with a seldom used character. In fact, that's what Perl does internally when you give several keys to index a hash:

$myhash{'key1', 'key2'};

is equivalent to:

$myhash{join("\x1c", 'key1', 'key2')};

ASCII 28 is considered a seldom used character, but you may use another one by changing $;.

Needless to say this is widely considered dirty. davorg's suggestion of using a hash of hashes of arrays is a lot neater.
