Perl::Critic::Policy::References::ProhibitDoubleSigils(3)
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.
