NAME

       Perl::Critic::Policy::ControlStructures::ProhibitDeepNests - Don't write deeply nested loops and
       conditionals.

AFFILIATION

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

DESCRIPTION

       Deeply nested code is often hard to understand and may be a sign that it needs to be refactored.  There
       are several good books on how to refactor code.  I like Martin Fowler's "Refactoring: Improving The
       Design of Existing Code".

CONFIGURATION

       The maximum number of nested control structures can be configured via a value for "max_nests" in a
       .perlcriticrc file.  Each for-loop, if-else, while, and until block is counted as one nest.  Postfix
       forms of these constructs are not counted.  The default maximum is 5.  Customization in a .perlcriticrc
       file looks like this:

           [ControlStructures::ProhibitDeepNests]
           max_nests = 3
