Perl::Critic::Policy::ClassHierarchies::ProhibitExplicitISA - Employ use base
instead of @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.
This Policy is not configurable except for the standard options.
Some people prefer parent over base.
