 readable using smart match:
 
-C<'/path/to/file'.IO ~~ :r>
+    C<'/path/to/file'.IO ~~ :r>
 
 You can, of course, use an already opened filehandle. Here, using the file
 handle C<$fh>, is an example, using the method syntax for the file test:
 
-C<$fh.r>
+    C<$fh.r>
 
 Most of the former filetests have colon equivalents for use with smart match:

-:d Directory
-:f File
-:l Symbolic link
-:r Readable
-:w Writable
-:x Executable
-:s Size
-:z Zero size
