Tricks of the Wizards

Tied Filehandles

Suppose you don't like the opendir/readdir interface to directories
Why not a regular filehandle?
Then you could do:

        use Dir;
        my $dh = Dir->open(".") or die ...;
        while (<$dh>) {
          # Do something with the filename in $_
        }
        close $dh;

We'll do this by tying the handle in $dh, which will allow us to overload the <...> operator on it
