a space is not null or empty, at least in perl its not considered to be. A space, as in " " or [^ ] is a space, it does contain a value, a space. With perl, false values are 0 (zero) and "". I think there is also one exception to that, a special false value in what is returned by one of perl functions but I can't remember which function. I don't think it has anything to do with the square brackets, but it would make no sense to use the square brackets (a character class) that contains no characters to match. I think it just boils down to the fact that spaces are not null or empty.
