#NAME

Perl::Critic::Policy::References::ProhibitDoubleSigils - Write @{ $array_ref } instead of @$array_ref.

#AFFILIATION

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

#DESCRIPTION

When dereferencing a reference, put braces around the reference to separate the sigils. Especially for newbies, the braces eliminate any potential confusion about the relative precedence of the sigils.

push @$array_ref, 'foo', 'bar', 'baz';      #not ok
push @{ $array_ref }, 'foo', 'bar', 'baz';  #ok

foreach ( keys %$hash_ref ){}               #not ok
foreach ( keys %{ $hash_ref } ){}           #ok

#CONFIGURATION

This Policy is not configurable except for the standard options.
