Adding Module fallback function

Hi! If you need help, I would like to try implementing a shadow module like this, but rather it senses your errors in the code first, and if there aren't any, the modules get reloaded. The way I would do this, would be to clone the modules, and then delete them, and if it hasn't got any errors, it pastes the modules and tries to see if there is any errors. Hope to get a reply!
