Doh!  I knew I was missing something.  What's silly is that I had done

Perl's chdir, chown, chmod, and chroot should all behave like its stat
unary operator, accepting either an expression for a filename, or a
filehandle (or nothing for some of them).  I submitted an RFE to the
perlbug mailing list regarding this earlier today, right before writing
my previous bugtraq note...
