About \d \w and \s
To clarify things, does the unicode variant treat byte strings as if they were iso-8859-1 encoded? (There's also the question of how the use locale variant treats character strings, currently it assumes the string was accidentally iso-8859-1 decoded except where it has characters with code higher than 255, but it's probably always an error to actually depend on this so it doesn't matter.)
Strangely, it seems I don't have any obfus that use syntax like m/foobar/and (the closest I have is y//or in Ode for getprotobyname) so for a change this will be a new feature of perl core that does not break any of my obfus.
