I think we need to find a better name, and a clearer explanation for what this does. "invert" doesn't mean much to me.

How about ```_classes_copy_invert_kept_repaired```?

(Note: I have put "copy" near the beginning, because as a general rule, we try to name all bundles that do similar things with the same prefix - for example package_install, package_install_version, etc)
