Perl::Critic::Policy::ClassHierarchies::ProhibitExplicitISA(3)

NAME
Perl::Critic::Policy::ClassHierarchies::ProhibitExplicitISA - Employ "use parent" instead of "@ISA".

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

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

The original version of this policy recommended base instead of parent, which is now obsolete.

CONFIGURATION
This Policy is not configurable except for the standard options.
