=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 L<Perl::Critic::Policy::Plicease::ProhibitArrayAssignAref>,
which is a fork 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.
