It doesn't fix Coro. What's the upside? It gives non-core CPAN module code the ability to mutate and change the inner workings of perl core. Isn't that what a lot of the more interesting hooks and features are for? I occasionally find myself wanting some hook or ability and get a little annoyed that there isn't one; but that's usually just down to insufficient foresight for someone to have added it, or considerations of the performance impact it would have (e.g. my desire to hook SvREFCNT_dec). Intentionally removing a hook that has been demonstrated to have use-cases seems a whole different thing. -- Paul "LeoNerd" Evans leonerd@leonerd.org.uk http://www.leonerd.org.uk/ | https://metacpan.org/author/PEVANS
