It would cause subroutine redefinition warnings and possibly duplicate resource initialisation and other such badness if the module really *was* loaded previously. Bad idea. I think what we really want is to add `use_fails`, which *would* be able to safely wipe the `%INC` entry after failure, because by its very meaning, that test function can make an assumption that is otherwise unsafe. But both it and `use_ok` should warn if they find the key already in `%INC`. Although, as I wrote in comment at Ovid’s, it is `require` in Perl itself that should really wipe the key whenever a) loading fails and b) the key was not already there. Who knows if it’s feasible to change that semantic at this late point, though. Regards, -- Aristotle Pagaltzis // <http://plasmasturm.org/>
