Perl::Critic::Policy::ClassHierarchies::ProhibitExplicitISA - Employ C<use base> instead of C<@ISA>.



NAME

Perl::Critic::Policy::ClassHierarchies::ProhibitExplicitISA - Employ use base instead of @ISA.


AFFILIATION

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


DESCRIPTION

Conway recommends employing use base qw(Foo) instead of the usual our @ISA = qw(Foo) because the former happens at compile time and the latter at runtime. The base pragma also automatically loads Foo for you so you save a line of easily-forgotten code.


CONFIGURATION

This Policy is not configurable except for the standard options.


NOTE

Some people prefer parent over base.
