NAME

Perl::Critic::Policy::References::ProhibitDoubleSigils

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
