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

AFFILIATION

Top

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

DESCRIPTION

Top

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

Top

This Policy is not configurable except for the standard options.
