=head1 NAME

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

=head1 DESCRIPTION

A common mistake is to assign values to an array but use arrayref brackets
C<[]> rather than parentheses C<()>. 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 the L<Perl::Critic::Pulp> policy
L<Perl::Critic::Policy::ValuesAndExpressions::ProhibitArrayAssignAref>, and
performs the same function but in the C<community> theme.

=head1 AFFILIATION

This policy is part of L<Perl::Critic::Community>.

=head1 CONFIGURATION

This policy is not configurable except for the standard options.
