If, though, I replace test_sub with a package method...

Class::Inner(3pm) User Contributed Perl Documentation Class::Inner(3pm)
NAME
Class::Inner - A perlish implementation of Java like inner classes
SYNOPSIS
use Class::Inner;
my $object = Class::Inner->new(
parent => 'ParentClass',
methods => { method => sub { ... } }, },
constructor => 'new',
args => [@constructor_args],
);
DESCRIPTION
Yet another implementation of an anonymous class with per object overrideable methods, but with the added attraction of sort of working
dispatch to the parent class's method.
METHODS
new HASH
Takes a hash like argument list with the following keys.
parent
The name of the parent class. Note that you can only get single inheritance with this or SUPER won't work.
methods
A hash, keys are method names, values are CODEREFs.
constructor
The name of the constructor method. Defaults to 'new'.
args
An anonymous array of arguments to pass to the constructor. Defaults to an empty list.
Returns an object in an 'anonymous' class which inherits from the parent class. This anonymous class has a couple of 'extra' methods:
SUPER
If you were to pass something like
$obj = Class::Inner->new(
parent => 'Parent',
methods => { method => sub { ...; $self->SUPER::method(@_) } },
);
then "$self-"gt"SUPER::method" almost certainly wouldn't do what you expect, so we provide the "SUPER" method which dispatches to
the parent implementation of the current method. There seems to be no good way of getting the full "SUPER::" functionality, but I'm
working on it.
DESTROY
Because Class::Inner works by creating a whole new class name for your object, it could potentially leak memory if you create a lot
of them. So we add a "DESTROY" method that removes the class from the symbol table once it's finished with.
If you need to override a parent's DESTROY method, adding a call to "Class::Inner::clean_symbol_table(ref $self)" to it. Do it at
the end of the method or your other method calls won't work.
clean_symbol_table
The helper subroutine that DESTROY uses to remove the class from the symbol table.
new_classname
Returns a name for the next anonymous class.

Thanks to the Iterative Software people: Leon Brocard, Natalie Ford and Dave Cross. Also, this module was written initially for use in the
PerlUnit project, AKA Test::Unit. Kudos to Christian Lemburg and the rest of that team.
SEE ALSO
There are a million and one differen Class constructors available on CPAN, none of them does quite what I want, so I wrote this one to add
to that population where hopefully it will live and thrive.
BUGS
Bound to be some. Actually the "SUPER" method is a workaround for what I consider to be a bug in perl.
