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.
