Perl::Critic::Policy::ClassHierarchies::ProhibitExplicitISA - Employ use base instead of @ISA.
use base
@ISA
This Policy is part of the core Perl::Critic distribution.
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.
use base qw(Foo)
our @ISA = qw(Foo)
Foo
This Policy is not configurable except for the standard options.
Some people prefer parent over base.
