+Nim generates some warnings and hints that may annoy the
 user. A mechanism for disabling certain messages is provided: Each hint
 and warning message is associated with a symbol. This is the message's
 identifier, which can be used to enable or disable the message by putting it
 in brackets following the pragma:
 
   ```Nim
-  {.hint[LineTooLong]: off.} # turn off the hint about too long lines
+  {.hint[XDeclaredButNotUsed]: off.} # Turn off the hint about declared but not used symbols.
   ```
 
 This is often better than disabling all warnings at once.
