Since you're asking about related modules, I have an Attribute::Context module on the CPAN. I released it years ago, no one used it, so now test failures are piling up with newer releases: http://search.cpan.org/dist/Attribute-Context/lib/Attribute/Context.pm
Maybe that will help? Cheers, Ovid -- IT consulting, training, international recruiting http://www.allaroundtheworld.fr/.
