=head1 VERSIONS
Depending on the version of strictures requested, different warnings will be
use strict;
use warnings FATAL => 'all';
- use warnings NONFATAL => 'deprecated', 'experimental';
+ use warnings NONFATAL => qw(
+ exec
+ recursion
+ internal
+ malloc
+ newline
+ experimental
+ deprecated
+ portable
+ );
+ no warnings 'once';
+
# and if in dev mode:
no indirect 'fatal';
no multidimensional;
no bareword::filehandles;
+Additionally, any warnings created by modules using L<warnings::register> or
+C<warnings::register_categories()> will not be fatalized.
