=head1 NAME

Perl::Critic::Policy::TestingAndDebugging::ProhibitProlongedStrictureOverride - Don't turn off strict for large blocks of code.

=head1 AFFILIATION

This Policy is part of the core L<Perl::Critic> distribution.


=head1 DESCRIPTION

Every agrees that C<use strict> is the first step to writing maintainable code
in Perl.  However, sometimes C<strict> is a little too strict.  In those
cases, you can turn it off briefly with a C<no strict> directive.

This policy checks that C<no strict> is only in effect for a small number of
statements.

=head1 CONFIGURATION

The default number of statements allowed per C<no strict> is three.  To
override this number, put the following in your F<.perlcriticrc>:

 [TestingAndDebugging::ProhibitProlongedStrictureOverride]
 statements = 5
