If you can come up with a 90% solution that covers traditional methods, Moose, Class::Accessor, and Class::Struct, I think you'll be in good shape.

For the rest, provide an easy way for me to specify the methods and other information manually. Either in my code or in another file. For modules I get from CPAN or elsewhere, it would need to be in a separate file that I could reuse between projects (and hopefully share with others). For my own modules, I'd prefer to have a way to embed the infomation in my code, but a separate file would be OK, too.

If you make it easy for me to build a plugin to provide automatic support for my personal method-maker du jour, so much the better.

By the way, thanks for all the effort you are putting into this project.
