And the point is...??? Unix does not prevent symbolic links from pointing
to a directory up the tree, so the same thing could happen.

This is Yet Another Reason why people should not try to reinvent the
wheel, but instead become familiar with the code that comes with Perl. It
is quite likely thut weird stuff like this is already dealt with,
especially in modules that come with the Perl core. It's also much faster
to learn how to use, say, File::Find than to write and debug your own.
