Class::insideout is a simple, safe and streamlined toolkit for building inside-out objects. unlike most other inside-out object building modules already on cpan, this module aims for minimalism and robustness:

* does not require derived classes to subclass it
* uses no source filters, attributes or check blocks
* supports any underlying object type including black-box inheritance
* does not leak memory on object destruction
* overloading-safe
* thread-safe for perl 5.8.5 or better
* mod_perl compatible
* makes no assumption about inheritance or initializer needs
it provides the minimal support necessary for creating safe inside-out objects and generating flexible accessors.
