Ah yes, nothing actually got released, but I thought there was something in the CVS. However, if I go back to it I'll likely be throwing everything away anyway, having learned what I need from the spike.

Ah yes, just checked again, CVS definitely has working code. Take a look at 'Refactor.pm' for the basic nastiness of how the method works. Reflex::Def::Module is also a source of scary magic...
