NAME

       Object::Deadly::_unsafe - Implementation for the deadly object

METHODS

       "$obj->DESTROY"
	   The DESTROY method doesn't die. This is defined so it won't be AUTOLOADed or fetched from UNIVERSAL.

       "$obj->isa"
       "$obj->can"
       "$obj->version"
       "$obj->DOES"
       "$obj->import"
       "$obj->require"
       "$obj->use"
       "$obj->blessed"
       "$obj->dump"
       "$obj->peek"
       "$obj->refaddr"
       "$obj->exports"
       "$obj->moniker"
       "$obj->plural_moniker"
       "$obj->which"
       "$obj->AUTOLOAD"
	   Each of AUTOLOAD, a named list of known UNIVERSAL functions and then a query for everything currently known are all implemented with
	   "Object::Deadly->get_death" to prevent anything from sneaking through to a successful call against something in UNIVERSAL.

	   That list of functions are what core perl uses plus a bunch from CPAN modules including UNIVERSAL, UNIVERSAL::require, UNIVERSAL::dump,
	   UNIVERSAL::exports, UNIVERSAL::moniker, UNIVERSAL::which. That's just the list as it exists today. If someone else creates a new one
	   and you load it, be sure to do it *prior* to loading this module so I can have at least a chance at noticing anything it's loaded.

NAME

       Perl::Critic::Policy::BuiltinFunctions::ProhibitUniversalIsa - Write "eval { $foo->isa($pkg) }" instead of "UNIVERSAL::isa($foo, $pkg)".

AFFILIATION

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

DESCRIPTION

	   print UNIVERSAL::isa($obj, 'Foo::Bar') ? 'yes' : 'no';  #not ok
	   print eval { $obj->isa('Foo::Bar') } ? 'yes' : 'no';    #ok

       As of Perl 5.9.3, the use of "UNIVERSAL::isa" as a function has been deprecated and the method form is preferred instead.  Formerly, the
       functional form was recommended because it gave valid results even when the object was "undef" or an unblessed scalar.  However, the
       functional form makes it impossible for packages to override "isa()", a technique which is crucial for implementing mock objects and some
       facades.

       Another alternative to UNIVERSAL::isa is the "_INSTANCE" method of Param::Util, which is faster.

       See the CPAN module UNIVERSAL::isa for an incendiary discussion of this topic.

CONFIGURATION

       This Policy is not configurable except for the standard options.
