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

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

DDEESSCCRRIIPPTTIIOONN
       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

CCOONNFFIIGGUURRAATTIIOONN
       This Policy is not configurable except for the standard options.
