 Extra testing is auto-enabled in checkouts only, so if you're the author
 of a strictures using module you need to run:
 
   cpan indirect multidimensional bareword::filehandles
 
 but these modules are not required by your users.

+should consider installing them, they're all great anti-footgun tools.
