Take a look at readdir. It doesn't return a list!

Um, look again.

readdir DIRHANDLE
Returns the next directory entry for a directory opened by "opendir". If used in list context, returns all the rest of the entries in the directory. If there are no more entries, returns an undefined value in scalar context or a null list in list context.
Using readdir in a list context is a frequently used idiom.
