Changes (by igloo):

  * keywords:  => warnings
  * difficulty:  => Unknown
  * milestone:  => _|_


Comment:

 Warnings are never going to be completely accurate, but this is certainly
 an example of a case that could be fixed.

 I'll set the milestone to `_|_`  as it would make sense to do it as part
 of a larger warnings overhaul.
