Funny that you mention the word "stable"... If you read 'perldoc perl58delta', you'll see that 5.6 versions of Perl used quicksort for the sort() function, which is under some circumstances an unstable sort algorithm. Versions 5.8 and above use mergesort, which is guaranteed to be stable. I refer you to 'perldoc sort' (it's a pragma, too) for more information. ... then there's the algorithmic complexity attacks against the hashing algorithm, and many other things which were fixed in the 5.8 line (like the potentially massive delay on creating threads, ...). You wouldn't want people to be able to guess your hash keys / values, would you? --=-ZOe9CZ1chPUKreb9OnF/ Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.6 (FreeBSD) iD8DBQBBZESPk/lo7zvzJioRAq5sAJ9TDymooptHXq5B6mtYFDNTsHssWwCgqMqU lRvAth3ONYcvxdtB7wf5UmA= =jIn+ -----END PGP SIGNATURE----- --=-ZOe9CZ1chPUKreb9OnF/--
