Perl::Critic::Policy::TestingAndDebugging::RequireUseWarnings - Always use warnings.
use warnings
This Policy is part of the core Perl::Critic distribution.
Using warnings, and paying attention to what they say, is probably the single most effective way to improve the quality of your code. This policy requires that the 'use warnings' statement must come before any other statements except package, require, and other use statements. Thus, all the code in the entire package will be affected.
'use warnings'
package
require
use
There are special exemptions for Moose and Moose::Role because they enforces strictness; e.g. 'use Moose' is treated as equivalent to 'use warnings'.
'use Moose'
This policy will not complain if the file explicitly states that it is compatible with a version of perl prior to 5.6 via an include statement, e.g. by having require 5.005 in it.
require 5.005
The maximum number of violations per document for this policy defaults to 1.
This Policy is not configurable except for the standard options.
