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.
