NAME

Perl::Critic::Policy::ClassHierarchies::ProhibitOneArgBless - Write "bless {}, $class;" instead of just "bless {};".

AFFILIATION

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

DESCRIPTION

Always use the two-argument form of "bless" because it allows subclasses to inherit your constructor.
     sub new {
         my $class = shift;
         my $self = bless {};          # not ok
         my $self = bless {}, $class;  # ok
         return $self;
     }
 
 

CONFIGURATION

This Policy is not configurable except for the standard options.
