66# fetch($name, \@args, $context)
67#
68# General purpose method for requesting instantiation of a plugin
69# object. The name of the plugin is passed as the first parameter.
70# The internal FACTORY lookup table is consulted to retrieve the
71# appropriate factory object or class name. If undefined, the _load()
72# method is called to attempt to load the module and return a factory
73# class/object which is then cached for subsequent use. A reference
74# to the calling context should be passed as the third parameter.
75# This is passed to the _load() class method. The new() method is
76# then called against the factory class name or prototype object to
77# instantiate a new plugin object, passing any arguments specified by
78# list reference as the second parameter. e.g. where $factory is the
79# class name 'MyClass', the new() method is called as a class method,
80# $factory->new(...), equivalent to MyClass->new(...) . Where
81# $factory is a prototype object, the new() method is called as an
82# object method, $myobject->new(...). This latter approach allows
83# plugins to act as Singletons, cache shared data, etc.
84#
85# Returns a reference to a plugin, (undef, STATUS_DECLINE) to decline
86# the request or ($error, STATUS_ERROR) on error.
