 You don't need to actually open a filehandle in the traditional way (although
 you can) to do a filetest. You can simply append C<.IO> to the filename. For
 instance, here is how to check if a file is readable using smartmatch:
-C<'/path/to/file'.IO ~~ :r>

 You can, of course, use an already opened filehandle. Here, using the filehandle
 C<$fh>, is an example, using the method syntax for the file test:
