=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|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
