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.
