Perl::Critic::Policy::Community::ArrayAssignAref(3pm)

NAME

Perl::Critic::Policy::Community::ArrayAssignAref - Don't assign an anonymous arrayref to an array

DESCRIPTION

A common mistake is to assign values to an array but use arrayref brackets "[]" rather than parentheses "()". This results in the array containing one element, an arrayref, which is usually unintended. If intended, the arrayref brackets can be wrapped in parentheses for clarity.

 @array = [];          # not ok
 @array = [1, 2, 3];   # not ok
 @array = ([1, 2, 3]); # ok

This policy is a subclass of Perl::Critic::Policy::Plicease::ProhibitArrayAssignAref, which is a fork of the Perl::Critic::Pulp policy Perl::Critic::Policy::ValuesAndExpressions::ProhibitArrayAssignAref, and performs the same function but in the "community" theme.

AFFILIATION

This policy is part of Perl::Critic::Community.

CONFIGURATION

This policy is not configurable except for the standard options.
