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.
