      I'm a bit confused by your post. Running your code, it prints "Empty arrays are undefined", as it should...

        5.6.1 gives me this (when warnings are turned on) 
        defined(@array) is deprecated at ./emptydefined.pl line 5.
        (Maybe you should just omit the defined()?)

Empty arrays are undefined

        However, 5.00503 does not trigger this warning.
