Why does this work? 
#!/usr/bin/perl -w
use strict;

opendir (TOPDIR,"$ENV{HOME}")
   or die "Thus shall ye likewise perish: $!";
close TOPDIR;
while ($_=readdir(TOPDIR)){
  print "$_\n";
}

This will read the _closed_ directory handle, without an error, if invoked as % perl test_file (where test_file) contains the above code.

But, I just discovered that if I chmod 0755 test_file, the code fails without a warning when invoked directly. So, I'm more confused than ever. What is happening here?
