NAMEPerl::Critic::Policy::References::ProhibitDoubleSigils - Write "@{ $array_ref }" instead of "@$array_ref". AFFILIATIONThis Policy is part of the core Perl::Critic distribution. DESCRIPTIONWhen 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 CONFIGURATIONThis Policy is not configurable except for the standard options.
