NAME

       Object::Deadly - An object that dies whenever examined

SYNOPSIS

	 use Object::Deadly;
	 use Test::Exception 'lives_ok';

	 # Test that a few functions inspect their parameters safely
	 lives_ok { some_function( Object::Deadly->new ) } 'some_function';
	 lives_ok { Dumper( Object::Deadly->new ) } 'Data::Dumper';

DESCRIPTION

       This object is meant to be used in testing. All possible overloading and method calls die. You can pass this object into methods which are
       not supposed to accidentally trigger any potentially overloading.

       This problem arose when testing Data::Dump::Streamer and Carp. The former was triggering overloaded object methods instead of just dumping
       their data. Data::Dump::Streamer is now safe for overloaded objects but it wouldn't have been unless it hadn't have been tested with a
       deadly, overloaded object.

METHODS

       "Object::Deadly->new()"
       "Object::Deadly->new( MESSAGE )"
	   The class method "Object::Deadly->new" returns an "Object::Deadly" object. Dies with a stack trace and a message when evaluated in any
	   context. The default message contains a stack trace from where the object is created.

       "Object::Deadly->new_with( REFERENCE )"
	   The class method "Object::Deadly->new_with" returns an "Object::Deadly" object. Dies with a stack trace and a message when evaluated in
	   any context. The default message contains a stack trace from where the object is created.

       "Object::Deadly->kill_function( FUNCTION NAME )"
       "Object::Deadly->kill_function( FUNCTION NAME, DEATH CODE REF )"
	   The class method kill_function accepts a function name like "isa", "can", or similar and creates a function in the
	   "Object::Deadly::_unsafe" class of the same name.

	   An optional second argument is a code reference to die with. This defaults to "Object::Deadly->can( '_death' )".

       "Object::Deadly->kill_UNIVERSAL"
	   This class method kills all currently known UNIVERSAL functions so they can't be called on a "Object::Deadly" object. This includes a
	   list of methods known to the author and then an inspection of UNIVERSAL::.

       "Object::Deadly->get_death"
	   Returns the function "Object::Deadly::_death".

PRIVATE FUNCTIONS

       The following functions are all private and not meant for public consumption.

       "_death( $obj )"
	   This function temporarilly reblesses the object into "Object::Deadly::_safe", extracts the message from inside of it, and "confess"'s
	   with it.
