23.23.109.103 Use of inherited AUTOLOAD for non-method Net::IPv4Addr::ipv4_checkip() is deprecated at number_test.pl line 15 (#1) (D deprecated) As an (ahem) accidental feature, AUTOLOAD subroutines are looked up as methods (using the @ISA hierarchy) even when the subroutines to be autoloaded were called as plain functions (e.g. Foo::bar()), not as methods (e.g. < Foo-bar() >> or < $obj-bar() >>). This bug will be rectified in future by using method lookup only for methods' AUTOLOADs. However, there is a significant base of existing code that may be using the old behavior. So, as an interim step, Perl currently issues an optional warning when non-methods use inherited AUTOLOADs. The simple rule is: Inheritance will not work when autoloading non-methods. The simple fix for old code is: In any module that used to depend on inheriting AUTOLOAD for non-methods from a base class named BaseClass, execute *AUTOLOAD = \&BaseClass::AUTOLOAD during startup. In code that currently says use AutoLoader; @ISA = qw(AutoLoader); you should remove AutoLoader from @ISA and change use AutoLoader; to use AutoLoader 'AUTOLOAD';.
