Perl::Critic::Policy::ControlStructures::ProhibitDeepNests
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''.
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
